Description Boris Kukushkin 2012-11-06 05:44:05 UTC

Application: rekonq (0.9.1)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-32-generic-pae i686
Distribution: Ubuntu 12.04.1 LTS

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

I was just giving Rekonq a test-drive: opened a couple of pages (Google and some text page, afair) in different tabs, closed the window (a question was asked whether I was going to close current tab only or all the windows). The window closed and I ended up with the crash report window.

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