Konqueror crashed when closing a tab. The best way I can explain what happened is I had about 8 tabs open, computer was under a pretty good load, things were running pretty slow, I clicked the 'x' to close the tab then due to the slow reaction of the computer I clicked the 'x' again, probably closing a second tab and then I received this dump:

Using host libthread_db library "/lib/libthread_db.so.1".
`system-supplied DSO at 0xffffe000' has disappeared; keeping its symbols.
[Thread debugging using libthread_db enabled]
