KDE Platform Version: 4.10.00
Qt Version: 4.8.4
Operating System: Linux 3.8.0-6-generic x86_64
Distribution: Ubuntu Raring Ringtail (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
Initially I had a number of tabs open. As I finished reading the pages, I closed the tabs and then quit rekonq when reaching the last pages.

-- Backtrace:
Application: rekonq (rekonq), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
