           Summary: File->Open Crashes upon loading large a file in
                    UMLClassifier::getOpList(bool)
           Product: umbrello
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: umbrello-devel.kde.org
        ReportedBy: holger.lehmann catworkx de


Version:           1.2.90 (kdesdk-040402) (using KDE KDE 3.2.1)
Installed from:    Compiled From Sources
Compiler:          gcc 3.3 
OS:          Linux

I was editing a larger class having approx. 130 attributes.
There are two interfaces (couple of functions, around 15) and on more class without no attributes.
Along with this was a state diagram and approx. 20 use cases.
After saving the file, exiting umbrello, staring umbrello and reopening this file umrello just crashed.
This happened to the version (1.2.1) supplied in the KDE 3.2.1 RPMS for SuSE 8.2 as well as the sourcecode, version (1.2.90), from the kdesdk-040402.tar.bz2 file.

This is the traceback from the 1.2.90 version.
