Bug 332608

Application: konqueror (4.12.3)
KDE Platform Version: 4.12.3
Qt Version: 4.8.5
Operating System: Linux 3.13.6-200.fc20.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

I was reading an article on deviantart.com. I had not pressed any buttons nor moved my mouse for about a minute when Konqueror suddenly closed. There were no warning signs at all. Normally, Konqueror is capable of handling deviantart.com well, better than Firefox even! Some part of Konqueror must have decayed over the past few weeks.

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