Bug 305156

Application: krunner (0.1)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.2
Operating System: Linux 3.3.8-gentoo x86_64
Distribution: "Gentoo Base System release 2.1"

-- Information about the crash:
- What I was doing when the application crashed:

There was a popup thing at the top of the screen, into which I typed Desktop/mp (to find a file which I had stored to Desktop folder in my home directory). But it wasn't shown in the dropdown menu, so I typed backspace twice to get back to just after the /. I got this crash message then.

I tried to do the same one more time and then it did not crash.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Komentojen suoritus (kdeinit4), signal: Segmentation fault
