           Summary: Kontact crashes when playing a video within akregator
           Product: kontact
           Version: 4.4.2
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: lelamal at alice.it


Version:           4.4.2 (using KDE 4.4.2)
OS:                Linux
Installed from:    Ubuntu Packages

I was reading an article on this page
http://www.ubuntugeek.com/how-to-install-a-script-for-amarok.html, and when I
clicked on the link to check the suggested video
(http://blip.tv/file/get/Apachelogger-InstallAmarokScripts606.ogv) the page
tried to load, but ultimately failed and Kontact crashed.

I'm on Kubuntu 10.04 LTS. The crash can be reproduced every time. Since a
useful backtrace could not be generated, I tried to install the debugging
symbols but some were not found. I saved the information collected thus far to
manually report the bug, and they are as follows:

Application: Kontact (kontact), signal: Segmentation fault
