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-r1 x86_64

What I was doing when the application crashed:
Crash is dependent on web page which is actually loaded, I think there is somewhere memory corruption, page seems to be little buggy (http://uloz.to) but should be without crash all time. I got only flash plugin installed, and this is one page where konqueror crashes for me - I want to something download from this page, then I click to backward button (more times) in navigation and I got message box with SIGSEGV 11 - but it is randomly.

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