Application: krunner (0.1)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-24-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
Alt+F2, enter a search term "NetworkManager" that is in some of my text file.  KRunner shows the start menu items.  After a delay of about 8 seconds, it adds strigi search results.  When I clicked on KRunner, it crashed.  But I just tried to reproduce and it didn't crash.  This crash seems to be in QThread handling rather than nepomuk/strigi internals.

 -- Backtrace:
Application: Run Command Interface (kdeinit4), signal: Segmentation fault
