-- Information about the crash:
The crash occures as, I tried to access a PDF file at IEEE Xplore (http://ieeexplore.ieee.org). In fact Konqueror seem crash on all inline pdf links. In other browsers I didn't observed such a behaviour. This behaves quite analog to my OGG video bug, I reported yesterday.

The crash can be reproduced every time.

 -- Backtrace:
Application: Konqueror (konqueror), signal: Illegal instruction
