i can't recall what i was doing (other applciations,etc). i don't know a way to reproduce yet.
Comment 6 Nelson Chan 2009-05-08 17:41:31 UTC 
I have once again produced this bug  i think, but still not yet a confirmed way to reproduce it. what i was doing was start a new search while krunner is trying to terminate a process which i told it to.
Here is the backtrace for this time:

Hope it helps!
Comment 7 Nelson Chan 2009-05-08 17:50:57 UTC 
Yea, starting a new search while terminating a process seems to be able to reproduce the crash at will.
