does not open Firefox

It seems that it fails to open the web browser. If you run 'ubuntu-bug' on the command line, do you see any error messages? What does

  gconftool --get /desktop/gnome/url-handlers/http/command

say?

From the command line, ubuntu-bug says:
matt@matts-laptop:~$ ubuntu-bug
GTK Accessibility Module initialized
matt@matts-laptop:~$ GTK Accessibility Module initialized
Error: Failed to send command: 500 command not parseable

matt@matts-laptop:~$ gconftool --get /desktop/gnome/url-handlers/http/command
firefox -remote "openurl(%s,new-tab)"

Hmm, I enabled a11y in Gnome and changed the gconf key to your value, but it works for me. Seb, Henrik, does that 'Error: Failed to send command: 500 command not parseable' say anything to you? I do not get that one.

no idea about it, no

I saw some updates come through, so tried this again. Now, I get this error:

$ ubuntu-bug
GTK Accessibility Module initialized
GTK Accessibility Module initialized
matt@matts-laptop:/tmp/lphelpwiki$ The program 'firefox-bin' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 1949 error_code 3 request_code 20 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

apport has generally worked fine for with AT-SPI on. Matt, does this still happen with AT-SPI off?

I tried it as is and got the same error I posted above. THen, I went to System -> Assistive Technology Preferences and unchecked "Enable Assistive Technologies."

No change. If that's not what you meant by AT-SPI let me know and I can try something else.

Ran into this problem as MusicBrainz Picard was unable to open the browser (it's not Apport-specific).

Quoting Matthew Nuzum:

matt@matts-laptop:~$ gconftool --get /desktop/gnome/url-handlers/http/command
firefox -remote "openurl(%s,new-tab)"

It was the same in my installation. The problem is the presence of the double quotes. The fix is simple:

gconftool --set /desktop/gnome/url-handlers/http/command --type=string 'firefox -remote openurl(%s,new-tab)'

This bug should probably be reassigned somewhere, but I am not familiar enough with Gnome to say if it's Firefox or GConf that's at fault here for defaulting to the broken value.

I can reproduce this error :
"Error: Failed to send command: 500 command not parseable"

From Python (with a local html file called index.html) :

>>> import webbrowser
>>> webbrowser.open("index.html")
True
>>> Error: Failed to send command: 500 command not parseable

Another way to reproduce this error :
"Error: Failed to send command: 500 command not parseable"

From Python :

>>> import webbrowser
>>> webbrowser.open("helloPython.html")
True
>>> Error: Failed to send command: 500 command not parseable

KeyboardInterrupt
>>> webbrowser.open_new("http://www.python.org/doc")
True
>>> Error: Failed to send command: 500 command not parseable

I forgot to mention that I'm running Ubuntu Feisty with firefox version : 2.0.0.4+1-0ubuntu1 and python2.5 version : 2.5.1-0ubuntu1

This is on gutsy machine. First the specs.

python= 2.5.1-1ubuntu4
firefox=2.0.0.6+2-0ubuntu2
firefox-granparadiso=3.0~alpha7-0ubuntu3

Preferred applications in Settings have set as firefox-granparadiso

but gconftool shows it as :-

shirish@Mugglewille:~$ gconftool --get /desktop/gnome/url-handlers/http/command
firefox %s

Doing bug-buddy gives a PC GetModule message and spawns another firefox window even though firefox-granparadiso is already running & is in preferred applications.

[Expired for apport (Ubuntu) because there has been no activity for 60 days.]

I'm seeing the same problem here on Feisty. Following Tore Anderson's gconftool suggestion seems to have done the trick.

I fixed the problem
The problem is not with ubuntu one is about the configuration of gnome about opening the browser
Try this in console. It works for me

gconftool --set /desktop/gnome/url-handlers/http/command --type=string 'firefox %s'
