Bug 250416

Application: rekonq (0.5.86)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.32-24-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

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

rekonq crashes 100% every time, when I try to write something in the URL bar. browsing with help of the bookmark toolbar is no problem, but when I writing something in the URL bar, the bar is expanding (showing up possible entries) and then rekonq is crashing.
It does not matter, what I'm writing:
Typing 'a' and waiting a little bit (maybe 0,5 s) results in the same as writing 'www.google.' -> crash.

Hope this is a bit helpful.

The crash can be reproduced every time.

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