           Summary: Crash when turning off C++ generator
           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

This time it is a little bit harder to crash Umbrello, but it works.

1. Load Umbrello
2. Change active language to Java and click for a new document
3. Change active language to PHP and click for a new document
4. Change active language to C++ and click for a new document
5. Go on changing the language till it crashes
