[GUTSY] firefox crashed

Thank you samyonair for submitting this report.

Could you please try to obtain a backtrace by following the instructions
on [1], or upload the crash report that probably was generated during
the crash and that should be located at /var/crash/ to [2].

Please indicate which extensions/plugins do you have enabled; and if
this crash is reproducible describe the steps that lead to it (it is
very important for us to have a test case for each crash).

This will greatly aid us in tracking down your problem.

Thanks in advance.

please start firefox from terminal like:

 strace -e open -f firefox &> /tmp/strace.log

and attach the strace.log you get once it crashed.

Sorry that I post late but the because of a Harddisk failure, the Instalation is crashed so I can' t reproduce the failure at the time I've no time to install something because I need to buy a Hardisk first.

I have the same problem. I have attached the strace output. It looks like there is a permissions problem on the msttcorefonts perhaps.

sudo chmod +r /usr/share/fonts/truetype/msfonts/*.ttf

Seems to work now.

I had the same problem.
Running firefox with root privileges (sudo firefox) worked, thus hinting that permission rights might cause the problem.
I do not have a "msfonts" subdirectory, but rather "windowsfonts".
My solution was therefore:
sudo chmod +r /usr/share/fonts/truetype/windowsfonts/*.ttf

I don't have msfonts or windowsfonts installed and I am getting firefox crashes. Running from the terminal I would get this after the crash:

firefox
QSettings::sync: filename is null/empty
Segmentation fault (core dumped)

I have run with strace and attached the result.

my strace attached

I have the same problem with firefox and msttcorefonts. It seems that each time I want to access a webpage where some MS fonts are used, e.g. ubuntuforums.org, firefox quits unconditionally. Changing the permission did not help so far. However, starting up firefox with root privileges did not cause the crash. So, there must be a problem with the permissions... Attached is my strace.log.

I think same problem. It's solid, whether in safemode or not. Doesn't happen if I sudo firefox.

"firefox -safemode

(gecko:12885): Pango-WARNING **: failed to create cairo scaled font, expect ugly output. the offending font is 'Lucida Grande 8.25'
Segmentation fault (core dumped) "

I have run "sudo find /usr/share/fonts/truetype/ -iname "*.ttf" -print0 | xargs -0 sudo chmod +r" so all my tt fonts are readable. Makes no difference.

I attach a gdb log.

I think Bug #152609 is a duplicate, but it contains a work-around which worked for me: export MOZ_DISABLE_PANGO=1, then run firefox.

And now I have traced my problem to extension firebug. Removed it, removed the MOZ_.... work-around above, and now firefox is fine for me. Hope that helps somebody else.

But if you ran firefox in safe mode, all extensions (including Firebug) should be disabled.
In my case, uninstalling FireBug did not help (but I think it could have not uninstalled completely, because now I get at every firefox starup a window titled NS_ERROR_FAILURE with message:
  Componen returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIStringBundle.formatStringFromName]

MOZ_DISABLE_PANGO=1 works for me, the same with sudo firefox although there are the ugly solutions.

When I normally run firefox it segfaults (the number xxxx after the "line 131: xxxx" changes with every launch)

(gecko:23637): Pango-WARNING **: failed to create cairo scaled font, expect ugly output. the offending font is 'Arial 9'
/usr/lib/firefox/run-mozilla.sh: line 131: 23637 Segmentation fault (core dumped) "$prog" ${1+"$@"}

Attached strace

What is more interesting, in my case when i run firefox from the commandline with:
  $ MOZ_DISABLE_PANGO=0 firefox

It also does not crash. Does it meas that problem lies elsewhere?

I have a similar problem on Gutsy, but with FF 3 (a nightly build)..
I get those Pango-WARNING messages but the FF does not crash

I have searched the internet for a solution of that before subscribed problem.
In my case
  >sudo chmod +r `locate .ttf|grep -i "ttf$"
solved the problem. Thanx to you all (to unix cracks... is there a better solution)

It was the rights of maybe some ttf-files. But I can't tell which one it was, because I've run the command first. :(

Maybe another user can post the difference (just guessing the commands)
 > ls -l `locate .ttf|grep -i "ttf$" >> ttf-files.before.log
 > sudo chmod +r `locate .ttf|grep -i "ttf$"
 > ls -l `locate .ttf|grep -i "ttf$" >> ttf-files.after.log
 > diff ttf-files.before.log ttf-files.after.log
and paste the difference here.

I fogort to tell, that to set the rights solves another problem. Maybe one of you find the right bug report
and can change the next ubuntu update. Please mark this update urgent, because its an error I think.

The problem was (sorry I have a german version and I try to guess the english names)
  System -> Settings -> "Display" -> Fonds
The Arial fond was not displayed in the preview windows. There were only empty rectangles.

Hope this helps.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with latest Ubuntu release? Thanks in advance.

To respond to Connor's request...

Eventually the problem was solved when I found some fonts (Lucida Grande?) which did not have the read attribute. I think from memory something like "sudo chmod +r /usr/local/share/fonts/*" fixed it for me. So somehow I guess I installed some restricted fonts incorrectly.

As far as I am concerned the problem is resolved.

Hi

I can't tell anymore as I have switched to debian some time ago. So
closing this report would be ok for me
