New crash information added by DrKonqi

umbrello (2.12.99-11cb9f4) on KDE Platform 4.11.3 using Qt 4.8.5

- What I was doing when the application crashed:
I imported c++ classes from openscenegraph source (subdirectory
include/osgViewer)

This happens when the undo support and the code import option "create artificat
on each imported file" are enabled. 

The reason: In void CmdCreateUMLObject::redo(), the UMLObject is added to the
parent in UMLPackage::addObject(). In the crash case the parent is an
UMLArtificat instance, which do not derive from UMLPackage. addObject()
accesses m_objects to see if the object has already been added and crashes
because of invalid class type. 

A fix would be either
- derive UMLArtifact from UMLPackage (and load/save child relations from/to xmi
file)
- do not use UMLArtifact objects as parent (second best solution, because
relations will be lost)
