If you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? Also, what KDE and Qt version are you using? This looks like an Qt bug (already fixed in qt-copy and waiting for 4.4.4 and 4.5) Thanks :)
The reporter sent me an email: KDE version is 4.2RC, and Qt~~~,I don't know how to see which version I using. (Google Translation): I think the KDE desktop zoom (the upper right corner to start inside the magnifying glass) is very strange, after each restart, I always will be to add their own desktop, and then delete those desktop appeared. This time, one plus two plus me, I have to delete the two, and gave me the collapse of the report.
just want to add the info, that i have the same crash with the same dump, but using a newer configuration: openSUSE 11.1, ATI 4850 KDE 4.2.1 from opensuse factory build, qt 4.4.x Running apps: Firefox 3.0.7, Thunderbird 2.0.0.19, YaST control center In case i didn't see the difference: Anwendung: Plasma-Arbeitsfläche (plasma), Signal SIGSEGV [Current thread is 1 (Thread 0xb51ad710 (LWP 4600))] Thread 3 (Thread 0xa984eb90 (LWP 4607)): #0 0xffffe430 in __kernel_vsyscall () #1 0xb6492c35 in pthread_cond_wait@@GLIBC_2.3.2 () from /lib/libpthread.so.0 #2 0xb64f2872 in QWaitCondition::wait(QMutex*, unsigned long) () from /usr/lib/libQtCore.so.4 #3 0xb78ef0d2 in ??

@ Peter: your crash backtrace is a bit different, therefore , it's a different crash: probably bug 178076. Thanks
Sorry, there are two other infos, that i did forget to mention: - Plasma restarted and i could continue my work -> that is why i think it is different from bug 178076 - i'm updating from suse factory build nearly every day. -> maybe it is just a problem resulting from updating and going on working without a reboot.
