Bug 311326

Application: konqueror (4.9.3)
KDE Platform Version: 4.9.3
Qt Version: 4.8.4
Operating System: Linux 3.6.9-4.fc18.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

i) I was looking at the website met.hu in a tab, with another tab open
ii) Closed tab containing met.hu
iii) Konqueror crashed

No other applications were open at the time apart from Amarok.

The crash can be reproduced some of the time.

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