           Summary: Adding two operations with same name, but different
                    parameters causes crash
           Product: umbrello
           Version: unspecified
          Platform: SuSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: umbrello-devel at kde.org
        ReportedBy: th.fischer at gmx.net


Version:            (using KDE KDE 3.2.0)
Installed from:    SuSE RPMs
OS:          Linux

Umbrello crashes when an operation is added to a class that has already an operation with the same name, but different parameters.
How to reproduce: Create a new document. In "class diagram" add a new class, say "Test". Add a new operation named "op" and a parameter "int a". Add another operation named "op", too. Add to the new "op" the parameter "double b". Pressing OK (to add the new operation to the class) causes the crash.
