           Summary: Crash when changing code generator to C++
           Product: umbrello
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: umbrello-devel.kde.org
        ReportedBy: seb_stein gmx de


Version:           1.3.0 (using KDE 3.2.3, compiled sources)
Compiler:          gcc version 3.3.3
OS:                Linux (i686) release 2.4.26

1. Load Umbrello, C++ must be already selected
2. Select an old style code generator like PHP 
3. Click in the toolbar on new document
4. Change active language to C++
-> Crash

Maybe this is also the reason for bug 77645. But if I delete all datatypes
after step 1, it doesn't crash.
