Just this time, when I close rekonq while loading pages. Otherwise (if I doesn't try to close it while loading process) rekonq always load all this tabs without crash.

Created attachment 76359 [details]
New crash information added by DrKonqi

rekonq (2.0) on KDE Platform 4.9.97 using Qt 4.8.3

- What I was doing when the application crashed:

To be more specific:
> Just this time, when I close rekonq while loading pages.
rekonq crash every time when I close it while pages is still loading (at least for me).
