Bug 276241

Application: krunner (0.1)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
The calculator crashes every time I type "=1/1 eV" - probably because there is no convenient unit that is inverse of energy.

The crash can be reproduced every time.

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