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

When logging in to http://cloud9ide.com (you can sign up for a free account for testing) the a blank page opens (http://cloud9ide.com/dashboard.html) and if I left click on it Rekonq crashes.

The crash can be reproduced every time.

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