Application: konqueror (4.5.00 (KDE 4.5.0))
KDE Platform Version: 4.5.00 (KDE 4.5.0)
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:

Browsing with konqueror

- Unusual behavior I noticed:

A strange window pops up when browsing, and when i close it, konqueror crashes. I think it might be related to the flash-plugin wrapper.

The crash can be reproduced every time.

-- Backtrace:
Application: Konqueror (konqueror), signal: Bus error
