Description of problem: I have a completely updated Fedora 12 system. Compiz was disabled by default on install. When I go to the desktop-effects in System - Preferences, and select "Compiz", it presents me with an option to either "Use Previous Settings", or "Keep Settings". If I select "Keep Settings", everything is fine and compiz works well and the effects are displayed. If I instead select "Use Previous Settings", abrt reports that compiz has segfaulted. There is no visible indication of the segfault except for the abrt warning. I can still close desktop-effects, and use my system normally. Or I can instead choose to enable compiz again. This leads me to wonder abrt is reporting a false-positive segfault. abrt is also unable to generate a backtrace which I can use to report. I have the corresponding debug packages installed, yet abrt is not generating a backtrace (for which I will file a separate bug). Can I somehow manually generate backtrace, or confirm whether compiz is actually segfaulting in the first place? Version-Release number of selected component (if applicable): compiz-0.8.2-19.fc12.x86_64 How reproducible: Always Steps to Reproduce: 1. System - Preferences - Desktop Effects 2. Select "Compiz" 3. Click on "Use Previous Settings" Actual results: abrt reports a segfault Expected results: No segfault Additional info: I have installed abrt from updates-testing in order to try and generate a backtrace, but even that isn't working out.
Some plugins do segfault when being unloaded, there is a fixed package in updates-testing, I will push it to stable once I fix the regression introduced in it (the wall plugin is broken). Can you you confirm that it does not segfault with the updates-testing version?
After installing the version from updates-testing, it does not get enabled at all. I don't see any segfaults, but I can't determine whether that is because the bug is fixed, or because compiz doesn't load at all. Using desktop-effects killed all window managers, I had to go to vt2 and use metacity --replace. Using compiz --replace from the terminal shows this output: $ compiz --replace compiz (video) - Warn: No 8 bit GLX pixmap format, disabling YV12 image format compiz: symbol lookup error: /usr/lib64/compiz/libwall.so: undefined symbol: getCompPluginInfo I think it's the broken wall plugin that you mentioned.

Yes that is the wall plugin regression, thanks for testing though.
Hi All. Adel, thanks for handling (had barely the time lastely to dedicate time triaging). Continue doing a good job maintaining some folks´s preferred package :-) Regards. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers *** This bug has been marked as a duplicate of bug 545516 ***
