Application that crashed: konqueror
Version of the application: 4.3.5 (KDE 4.3.5) "release 0"
KDE Version: 4.3.5 (KDE 4.3.5) "release 0"
Qt Version: 4.5.3
Operating System: Linux 2.6.31.12-0.2-desktop x86_64
Distribution: "openSUSE 11.2 (x86_64)"

What I was doing when the application crashed:
I was browsing for a while when opened a link to a blog. After switching to the corresponding tab in which the blog was loading I opened three of four tabs with different blog entries and the Konqueror's performance dropped a lot, becoming sluggish. Then I tried to close those tabs and Konqueror crashed.
During that time the system resources usage exploded: the cpu arrived at 90ºC before konqueror crashed. 
This is the blog:
