Application: kontact (4.4.1)
KDE Platform Version: 4.4.1 (KDE 4.4.1)
Qt Version: 4.6.2
Operating System: Linux 2.6.31-gentoo-r6 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
When dragging urls from emails to my browser window (chromium), kontact itself or the kmail component sometimes crashes. Usually, when that happens, also chromium crashes, but not always. I'm not sure but I think this is only reproducable in multimonitor setups when dragging the link across screen borders and touching other programs during the drag. Never had this problem on my home pc with only one monitor attached.

The crash can be reproduced some of the time.

 -- Backtrace:
