Application that crashed: konqueror
Version of the application: 4.3.1 (KDE 4.3.1)
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.1
Operating System: Linux 2.6.30-gentoo-r4 x86_64

What I was doing when the application crashed:
I had two tabs open (http://winowin.de/30209 and a page on a pdassi account to download purchased products). When I wanted to close konqueror, it crashed with the backtrace below. Regrettably I cannot reproduce this crash.

 -- Backtrace:
