Application: plasma-desktop (0.3) KDE Platform Version: 4.4.92 (KDE 4.4.92 (KDE 4.5 RC2)) Qt Version: 4.7.0 Operating System: Linux 2.6.35-020635rc1-generic i686 Distribution: Ubuntu 10.04.1 LTS -- Information about the crash: - What I was doing when the application crashed: 1 - I unlock widgets (right click "unlock widgets") 2 - I move the mouse above the viewed folder's widget (my Desktop folder). The panel settings of the widget appears. 3 - the plasma crashes with black desktop then come back. 4 - When I move the mouse again above the widget, I have no more panel setting's appear and no more crash of plasma. 5 - I can reproduce that every time by "lock widgets" then "unlock widgets" then move mouse above widget. The crash can be reproduced every time. -- Backtrace: Application: Espace de travail Plasma (plasma-desktop), signal: Segmentation fault [Current thread is 1 (Thread 0xb337d720 (LWP 1784))] Thread 2 (Thread 0xaa5b8b70 (LWP 1788)): #0 0xb6600344 in __pthread_mutex_unlock_usercnt () from /lib/tls/i686/cmov/libpthread.so.0 #1 0xb778cbe6 in pthread_mutex_unlock () from /lib/tls/i686/cmov/libc.so.6 #2 0xb3adf326 in g_main_context_acquire () from /lib/libglib-2.0.so.0 #3 0xb3ae0e5e in ??

The Plasma team can't reproduce this with either Qt 4.6 or Qt 4.7 using today's build. The crash itself looks to be in Qt, though ... can you try to update to a newer Qt snapshot and/or update this report when you install a newer KDE SC to see if the problem resolves itself?
Created attachment 49996 [details] New crash information added by DrKonqi plasma-desktop (0.3) on KDE Platform 4.5.00 (KDE 4.5.0) using Qt 4.7.0 - What I was doing when the application crashed: I update KDE this morning : KDE version : 4.4.92 -> 4.5.0b Qt version : 4.7.0~beta2-0ubuntu1 -> 4.7.0~beta2-0ubuntu3 and I've the same crash when I move the mouse above the unlock widget. It's more difficult to have crash (I move several times quickly before crash) but it crashes. Then, no more panel setting. -- Backtrace (Reduced): #7 0xb5d1c3bc in commonEdge (this=0xbf8ddd8c, fi=36, si=-1) at painting/qpathclipper.cpp:1172 #8 QWingedEdge::addEdge (this=0xbf8ddd8c, fi=36, si=-1) at painting/qpathclipper.cpp:1232 #9 0xb5d22b03 in QWingedEdge::intersectAndAdd (this=0xbf8ddd8c) at painting/qpathclipper.cpp:849 #10 0xb5d233fb in QWingedEdge (this=0xbf8ddd8c, subject=..., clip=...) at painting/qpathclipper.cpp:876 #11 0xb5d239dc in QPathClipper::clip (this=0xbf8dde6c, operation=QPathClipper::BoolOr) at painting/qpathclipper.cpp:1668

Can you reproduce this crash with a newer version of kde? the backtrace is too old to be usefull. thank you!
