Comment 1 Andrea Diamantini 2011-02-28 22:41:22 UTC 
I cannot in any way reproduce your crash. Can you pls upgrade your system (Qt, KDE, rekonq) and try it again?
Comment 2 Stefan Münzner 2011-05-24 14:12:22 UTC 
Created attachment 60268 [details]
New crash information added by DrKonqi

rekonq (0.7.0) on KDE Platform 4.6.2 (4.6.2) using Qt 4.7.2

- What I was doing when the application crashed:

rekonq crashes when closing a tab (4th tab of 4 tabs in total).

Comment 3 Andrea Diamantini 2011-12-18 09:42:47 UTC 
This does not really seem a rekonq bug. Is this yet happening with rekonq 0.8.1, Qt 4.7.x, kdelibs 4.7.x?
