From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0) Description of problem: When logging off from KDE sometimes I get a coredump which gdb says belongs to "kdeinit: kdesktop". It happens randomly and I haven't figured out the cause. How reproducible: Sometimes Steps to Reproduce: 1. start kde 2. use it for some time 3. log off Actual Results: Sometimes I get a coredump from kdeinit: kdesktop at the time of logoff. Expected Results: It shouldn't dump core. Additional info:
Can't reproduce this; please attach a backtrace.
Same here. I find coredumps once in a while.
*** Bug 51430 has been marked as a duplicate of this bug. ***
I have a core file: see core-48750 in my home directory.
I'm having a similar problem with kdeinit, except it segfaults during normal operations (usually slider moves or window moves), which locks up KDE entirely. (ctl-alt-backspace does not kill the window manager, so a reboot is required.) I already tried rebuilding kdebase from the source RPM on my host, but the problem persists. The stack trace from the last crash: Core was generated by `kdeinit: kdesktop'. Program terminated with signal 11, Segmentation fault.

Since "no core files" is now the default and kdeinit does not give a "Segmentation fault" message I was fooled into thinking it was fixed, but no, it happens in Red Hat 7.2, but now it happens after _every_ logout from KDE.
