Application: krunner (0.1)
KDE Platform Version: 4.10.2
Qt Version: 4.8.4
Operating System: Linux 3.8.0-22-generic x86_64
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:
Typed '=rand(24' into krunner, perhaps with the closing parenthesis. It crashed before showing the result.
The problem occurs occasionally, though I haven't found a robust way to reproduce it.

-- Backtrace:
Application: Interfejs do uruchamiania poleceń (krunner), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
