Bug 307559

Application: rekonq (1.1)
KDE Platform Version: 4.9.1 "release 561"
Qt Version: 4.8.3
Operating System: Linux 3.4.6-2.10-desktop x86_64
Distribution: "openSUSE 12.2 (x86_64)"

-- Information about the crash:
rekonq just crashes after opening some tabs.
BTW: even if not crashing, the tab preview is just annoying, chromium does it better.

The crash can be reproduced some of the time.

-- Backtrace:
Application: rekonq (rekonq), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
