           Summary: Plasma crashes when accessing manually removed comic
           Product: plasma
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: plasma-bugs@kde.org
        ReportedBy: wonko@wonkology.org


Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.00 (4.7.0) (Compiled from sources)
Qt Version: 4.7.3
Operating System: Linux 2.6.38-pf8 x86_64
Distribution: "Gentoo Base System release 2.0.3"

-- Information about the crash:
I had a problem with the 'Tom des Tages' comic, see
http://opendesktop.org/content/show.php?content=112260 . But I thought maybe I
had an old version of the comic and it has been fixed already, so I manually
removed it with plasmapkg -t comic -r tom-des-tages.comic so I could install it
again. Sure, I shouldn't have clicked on the Tom cartoon tab while it was
uninstalled, but I don't think plasma should crash. I even cannot restart
plasma-desktop manually, it just eats CPU time but nothing happens.
