           Summary: use cases in diagrams not correctly handled
           Product: umbrello
           Version: unspecified
          Platform: SuSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: umbrello-devel at kde.org
        ReportedBy: Achim.Spangler at mnet-online.de


Version:           CVS current (using KDE KDE 3.1.2)
Installed from:    SuSE RPMs
Compiler:          g++ (GCC) 3.3 20030226 
OS:          Linux

If I try with current CVS version a xmi file with use case diagrams, all use case symbols have no label text.
Additionally I get a lot of debug messages:
WARNING:  Syncronize classifier code doc:0x99d2838
(I'm not shure if these warnings belong to the problem with use case labels).

I tried to see and change the properties of a use case symbol in a use case diagram
--> umbrello crashed with the following trace:

===>
I suspect that this depends on the changes on internal code edit for classes,
as some of the functions in the call stack sounds like class management and since
this error is new since the last changes of around a week ago.

####
You can reproduce it by simply:
a) create new project with one use case 
b) create one use case diagram with the use case of a) (label is correct!!)
c) save - reload
--> use case in diagram has no label any more -> real save/reload problem
d) try to change property
--> CRASH
