Application: rekonq (2.2.1)
KDE Platform Version: 4.10.2
Qt Version: 4.8.4
Operating System: Linux 3.8.0-19-generic i686
Distribution: Ubuntu 13.04

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

This consistantly happened when I was composing an email in GMail.
Just opened the compose window and it crashed after typing the to address.
Then it was restarted by the crash handler / assistant, straight into the compose window (is a layer which looks like a window; clever google) as I have restore tabs option set, and it crashes again!

The crash can be reproduced sometimes.

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