Description Elias Probst 2010-09-28 15:08:45 UTC

Application: krunner (0.1)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.6.3
Operating System: Linux 2.6.36-rc5+ x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:
→ Launched krunner through Alt+F2
→ Entered something like =0,25+0,25+0,5+0,5+(0,25*4) when suddenly the result didn't update anymore
→ krunner crashed producing the following backtrace:

The crash does not seem to be reproducible.

-- Backtrace:
Application: Oberfläche zur Ausführung von Befehlen (kdeinit4), signal: Segmentation fault
The current source language is "auto; currently asm".
