Bug 277436

Application: rekonq (0.7.0)
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:

I was closing Rekonq.

Specifically, if i click on a Bookmark folder, just to see which bookmarks are listed there and then close Rekonq, an error occured.
It doesn't come up with an error while browsing, just when i close the program.

The crash can be reproduced every time.

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