Bug 268659

Application: rekonq (0.6.80)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-6-generic-pae i686
Distribution: Ubuntu Natty (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
Typed gg rekonq and pressed enter instead of gg:rekonq .

- Observations : 
Whatever I type in the URL bar, if it's more than one word, using whitespace as separator will crash the application.

The crash can be reproduced every time.

-- Backtrace:
Application: rekonq (rekonq), signal: Segmentation fault
