           Summary: kbuildsycoca4 crashes because of malformed .desktop file
           Product: kde
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs kde org
        ReportedBy: bogdan_gr gmx net


Version:            (using KDE 4.0.2)
Installed from:    Ubuntu Packages
OS:                Linux

I had an application that installed the following .desktop file in /usr/share/applications/ :

#file start

When i log into KDE 4.0.2 kbuildsycoca4 crashes multiple times (about 6) and the DE never loads. The ";" in "MimeType=;" is the reason. Following is the relevant part in my ~/.xsession-errors. This bit is repeated about 6 times in the log and then silence. Notice that kbuildsycoca4 doesn't even report the problem that causes the crash.
