Bug 216984

Application that crashed: rekonq
Version of the application: 0.3.0
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.6.0
Operating System: Linux 2.6.31-15-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
rekonq chrashed as I closed a Tab via Ctrg+W. I don't know why rekonq did it but I hope that I can help to solve this.

 -- Backtrace:
Application: rekonq (rekonq), signal: Segmentation fault
The current source language is "auto; currently c++".
