Bug 236476

Application that crashed: konqueror
Version of the application: 4.3.2 (KDE 4.3.2)
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-21-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Clicked+dragged a link to Chrome. As the mouse hovered over Chrome (but before I released the link), Chrome crashed. Not every time, but at least once, Konqueror crashed also.

I've reported this to Chrome:

http://code.google.com/p/chromium/issues/detail?id=43347

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