           Summary: Kontact (or KMail) crashes sometimes when dragging
                    urls to chromium
           Product: kontact
           Version: 4.4.1
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: kai at kaishome.de


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:
Application: Kontact (kontact), signal: Segmentation fault
