Bug 319059

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:

rekonq was already running, with several open tabs. I clicked on a link on a webpage which would have opened a new webpage in a new tab. But somehow rekonq crashed, before the new tab could open..

-- Backtrace:
Application: rekonq (rekonq), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
