Bug Description

Binary package hint: compiz

Compiz crashes when ubuntu starts and then I press Alt+tab. As I can see, the source of the problem is Regex matching module. When I disable it (and the Animations module, which depends on Regex), the problem seems to disappear.

And the only thing that is saving face (with me) right now is this in a terminal window:

$ while [ 1 ] ; do compiz --replace; done

It is crashing and restarting (per the loop) with no discernible pattern.

This bug keeps on happening. Its been happening since 40 days. That is when i upgraded from maverick to NATTY. It happens on kernels 2.6.36, 2.6.38, the generic ubuntu kernel too. I tested it with 5 different kernels. The following message is found in /var/log/syslog

Apr 30 17:51:37 solidus-workstation kernel: [437609.857278] compiz[19952]: segfault at 10 ip 00007fa564066335 sp 00007fff096e1350 error 4 in libregex.so[7fa564061000+8000]

Long ago b4 the upgrade there was no problems with the 2.6.36 kernel. Therefore im sure its not a kernel problem. Moreover, it used to happen a lot b4 the last 2 compiz updates. Now it happens only twice or 3 times when i log in to the system nd then it takes a long time to happen again. Also if i logout nd log in again, the same story repeats where compiz crashes 2 or 3 times and then takes a very long time to crash . The crash occurs when new windows open such as when u open banshee or the sound preferences or any gtk window etc...

I seem to be having this a lot more when I'm running conky. I'm not sure if that's related.

The same issue ocurrs on Fedora 15, and ArchLinux with compiz 0.9.4, so this is an upstream compiz bug.
On Arch, the issue ocurrs whenever a tooltip is displayed, or a menu is opened. Disabling regex matching prevents these crashes.

Unfortunately I can't use compiz at all at the moment (because of #781804), so, please, anyone who confirmed the bug, produce the appropriate stacktrace.

Backtrace Edit (39.2 KiB, text/plain)

I'm including an attachment generated with compiz 0.9.4, though not on Ubuntu (my GF's laptop is the one with ubuntu, and she's on a long trip so I won't have access to it for some time).

I hope this helps, I've generated it following the instructions at https://wiki.ubuntu.com/Backtrace.

In any case, just get back to me.
The EXACT same compiz config does not crash on a different PC with the same software configuration (os, compiz version, etc). That one has intel video, and this one nvidia, that's the only difference I can think of.

Cheers!

I forgot to say; the crashes are not only when alt-tabbing, but also when opening menus, if I open File, then Edit, and go back and fourth a couple of times, I get the same crash. Disabling regex matching fixes BOTH crashes, so I've always considered them the same one.

Marking both arch and fedora tasks as invalid until such time as valid bug reports for those are provided. It is highly unlikely that ubuntu developers are going to work those distributions.

I first noticed this problem when I started running Conky. However, it had nothing to do with Conky itself, but rather with the rule I put in ccsm (CompizConfig Settings Manager) to disable shadows on the Conky window [i.e. Window Decorations -> Shadow Windows = (any) & !(class=Conky)]. This causes Compiz to segfault in libregex.so, probably because it's using regex to try to match the window class/title. To prove this, I stopped running Conky but left the rule in place and, sure enough, Compiz continues to crash at random times. Removing the rule fixed the intermittent crashes in my case.

I had this bug on ArchLinux and Fedora with compiz 0.9.4 on the same PC. Upgrading to compiz 0.9.5 (development release) fixed this issue, can someone verify this is also the case on ubuntu?

Removing window matching rules in Window Decorations -> Shadow Windows resolved the crashes for me, too (now I'm using devilspie to unshadow windows).

Window matching rules in other plugins (like Animations) work fine, so the Window Decorations plugin seems to be the source of trouble.

I'm running Ubuntu 11.04.

#22 is the perfect answer. Same effect here!

When I remove window matching rules in Window Decorations -> Shadow Windows my crashes are resolved =

i.e. Window Decorations -> Shadow Windows = (any) & !(class=Conky).

As part of the big bug clear up for 16.04 LTS I am marking this bug as Wont Fix.
These types of crasher are better handled by errors.ubutnu.com which can collate similar crash reports to help us identify persitent bugs rather than one-off crashes.
Sorry we are not able to help with this specific issue. If you are still experiencing this crash, please re-open the bug and add the tag "desktop-bugscrub-reopened". See https://wiki.ubuntu.com/BigDesktopBugScrub for more information.
