Application: konqueror (4.7.2 (4.7.2))
KDE Platform Version: 4.7.2 (4.7.2) (Compiled from sources)
Qt Version: 4.8.0
Operating System: Linux 3.1.0-7.fc16.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed: I was trying to open the KDE bug page to create an account so I could send a bug report. I had to install another web browser (Firefox) because Konqueror would not start (it crashed again) when I tried to launch it directly.

- Unusual behavior I noticed: The Konqueror web browser constantly crashes and will not work.

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