           Summary: crash in a class diagram when selecting an association
                    (or trying to delete it)
           Product: umbrello
           Version: unspecified
          Platform: Debian testing
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: umbrello-devel.kde.org
        ReportedBy: pjaaskel cs tut fi


Version:           CVS HEAD (using KDE KDE 3.3.0)
Installed from:    Debian testing/unstable Packages
Compiler:          g++ (GCC) 3.3.4 (Debian 1:3.3.4-11) 
OS:                Linux

When I select association and right-click or press delete with it, Umbrello crashes. I created a simple test case from the diagram where the problem occurs. This is not the same association
deletion crash bug I sent a patch for last night, it's a different beast I noted even earlier.
