Application: konqueror (4.9.5)
KDE Platform Version: 4.9.5
Qt Version: 4.8.4
Operating System: Linux 3.7.3-101.fc17.x86_64 x86_64
Distribution: "Fedora release 17 (Beefy Miracle)"

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

Loaded a web page from a local server in konqueror which reported a javascript bug. Pressed 'Debug' to open the debugger. Stepped through a few lines. Changed the underlying javascript and reloaded by pressing F5 in the konqueror window. This crashed konqueror.

The crash can be reproduced every time.

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