Application: konqueror (4.13.3)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.16.2-201.fc20.i686 i686
Distribution (Platform): Fedora RPMs

-- Information about the crash:
What I did:

- Open Konqueror,
- Open facebook.com (still/already logged into my account)
- Scrolling down, curser was over an Image.

Result: Konqueror crashed/dissapeared immediatly and the usual KDE crash message showed up.  

- Restarting Konqueror, restoring the session did work fine and I could use facebook without crashing again.

Additional Info:
Yesterday I've needet to install another OpenJDK and I've installed Iced Tea, since this, Konqueror has crashed a couple of times. Maybe it has something to do with OpenJDK or Iced Tea.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Konqueror (konqueror), signal: Segmentation fault
