Description of problem: kwin_opengl_test frequent corefiles. Version-Release number of selected component (if applicable): This code seems to be provided by kde4 which is at 4.5.5 levels in this FC 14 system How reproducible: Every time Steps to Reproduce: 1.The problem seems to appear when one logs out of a kde "session" 2. 3. Actual results: core file and NOT useful backtrace from the core file due to unknown symbols perhaps Expected results: clean and graceful logout without core files or back traces... Additional info:
Thanks for report, "debuginfo-install kdebase-workspace" runned as root should do the dirty job to clear out unknown symbols. Please attach the newly created backtrace (hopefully with all symbols).
Even if there are unknown symbols, we can still see the libraries involved (which often is mesa or *ahem* certain 3rd-party libGL modules that start with "N").
Created attachment 481907 [details] tar.gz file of files relating to this bug. Here's the current kernel line from my grub.conf... from another bug.

Howdy, Here's the gdb info from my latest core file of this problem. Here also is the lspci output for the display. THANKS for your help!

that's clearly mesa, reassigning.
Hi, I did a yum reinstall for the mesa-libGL files and the problem is now gone. Where did my versions come from? I have no clue. Thanks for all your help with this. George...
