Description Jonas Vejlin 2009-06-05 10:33:22 UTC

Version:            (using KDE 4.2.4)
OS:                Linux
Installed from:    Debian testing/unstable Packages

I was tapping trough all my porgrams when it crashed. Here the output
Program: KWin (kwin), signal SIGSEGV

Thread 1 (Thread 0xb539f730 (LWP 7510)):
#0  0xb7fa8424 in __kernel_vsyscall ()
#1  0xb7e22350 in nanosleep () from /lib/i686/cmov/libc.so.6
#2  0xb7e2218e in sleep () from /lib/i686/cmov/libc.so.6
#3  0xb7c420f8 in ?? () from /usr/lib/libkdeui.so.5
#4  0x00000000 in ?? ()

way to reproduce it:
Have a windows that is going to close wile tapping
tap unto the window closed.
crash

I was using syanptic and reloding the information about withc package
the repo did have.

After the crash it looks like plasma is reloding but only the Windows that was open before the crahs repair. No backgroud/wallpapir, no menus, no panels

Will give us a backtrace to double check. That one has too many ??

I just install some extra package and I got this from gdb;
Dette backtrace synes at være nytteløst.
Det er formodentlig fordi dine pakker er bygget på en måde som forhindrer oprettelse af ordentlige backtrace, eller at stakrammen blev alvorligt korrumperet under sammenbruddet.
