           Summary: KWin randomly crashing
           Product: kwin
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kwin-bugs-null@kde.org
        ReportedBy: ry@n.rix.si


Application: kwin (4.8.00 (4.8.0))
KDE Platform Version: 4.8.00 (4.8.0) (Compiled from sources)
Qt Version: 4.8.0
Operating System: Linux 3.2.5-3.fc16.i686.PAE i686
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- Unusual behavior I noticed:
KWin will crash with no really repeatable behavior. It looks like in the
backtrace it's loading the system liboxygenstyle, shouldn't it be loading the
one under my source build? This occured under (master pre-4.8 + distro 4.7) as
well as the (master pre4.9 + distro 4.8) in the same invalidateCaches function.

This is using OpenGL backend on:
OpenGL vendor string: Tungsten Graphics, Inc
OpenGL renderer string: Mesa DRI Mobile Intel ® GM45 Express Chipset 
OpenGL version string: 2.1 Mesa 7.11.2

The crash can be reproduced some of the time.

-- Backtrace:
Application: KWin (kwin), signal: Segmentation fault
Using host libthread_db library "/lib/libthread_db.so.1".
