Application: krunner (0.1)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.7.3
Operating System: Linux 2.6.38-2-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
I was simply looking for "kdirstat", not installed on the system, led to a crash as soon as I pressed the "tab" key to select one of the results shown. Interestingly, this happened before any document containing the keyword was shown. 
I tried to repeat the search with the same search terms, and it was successful, showing both applications with a similar name and documents containing the word.

The crash can be reproduced some of the time.

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