Application: konqueror (4.6.5 (4.6.5))
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.3
Operating System: Linux 3.0.4 x86_64
Distribution: Debian GNU/Linux unstable (sid)

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

I had konqueror opened for a while, I usually have lots of tabs and several windows opened. This is the third strange crash I have had in the latest days. These all were pointer and KJS related, but I couldn't figure out a common cause. Konqueror + KHTML has always been quite stable to me.

Please, let me know how I could focus this sparse bug report.

Regards,

The crash can be reproduced some of the time.
