Application that crashed: konqueror
Version of the application: 4.3.00 (KDE 4.3.0)
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.30-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

What I was doing when the application crashed:
When adding an image to the adblock list from the page http://www.ddj.com/architect/184405849, konqueror suddenly closed due to a seg fault.  It appears that some memory was corrupted, as at least two different objects in memory shared an unusal address (0x20).  The address added was http://cmpnet.com/ .

 -- Backtrace:
Application: Konqueror (kdeinit4), signal: Segmentation fault
