Whilst typing a command in krunner it sometimes crashes. Not everytime - I haven't managed to reproduce it reliably. It happens sometimes when there are no other open programs. Description looks similar to #157230, but backtrace is different, so posting in case it is useful.

Created attachment 25697 [details] bugtrace when krunner crashes on me. Similar to the bugtrace above. As originally said, this bug is intermittent. It does not happen all the time. And krunner can be run again just after a crash and it works properly for the same command. I have compiled kde 4.1 from svn (rev: 825601) on openSUSE 11.0 x86_64 machine. gcc (SUSE Linux) 4.3.1 20080507 (prerelease) [gcc-4_3-branch revision 135036]

Any news about this crash ? KRunner on KDE4.2.3+/4.3 is a LOT more stable. Thanks
Closing as WORKSFORME. (now there are other KRunner crashes, with updated backtraces)
