Bug 288879

Application: rekonq (0.8.0)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.3
Operating System: Linux 3.1.5-zen-thinkpad-r61 x86_64
Distribution: Debian GNU/Linux testing (wheezy)

-- Information about the crash:
During my web browsing session if I open many tabs (>= 6-8) the application crash.

The crash occurs while the other tabs are loading, usually I don't have time to act in any way, if I open many tabs at one time the crash occurs in less than 1 second.
It doesn't seem to depend on the contents of the tabs, the application closes before the tabs are completely loaded.

It happens every time I open too many tabs.

The crash can be reproduced every time.

-- Backtrace:
Application: rekonq (rekonq), signal: Segmentation fault
