Bug 222093

Application: rekonq (0.3.0)
KDE Platform Version: 4.3.85 (KDE 4.3.85 (KDE 4.4 Beta2))
Qt Version: 4.6.0
Operating System: Linux 2.6.31-16-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
This is about the 4th time that rekonq has crashed after I opened a new tab and entered information. There seems to be no delay in terms of contacting the server etc. Like the act of either entering the data or pressing enter to initiate the server contact kills rekonq

The crash can be reproduced some of the times.

 -- Backtrace:
Application: rekonq (kdeinit4), signal: Segmentation fault
