Please provide a testcase xmi file because it looks data specific.

This is the XML file with which to work, to have this open and try to open
another umbrello stops.

Comment 4 Ralf Habacker 2016-08-30 05:28:48 UTC 
>#7 0xffffffff in __dynamic_cast () at /lib/libstdc++.so.6 
>#8 0x082bd338 in ClassifierWidget::paint(QPainter*, QStyleOptionGraphicsItem const*, QWidget*) ()
The callstack indicates that the crash happens somewhere in ClassifierWidget::paint() performing an invalid dynamic cast. 
An invalid cast is performed in classifier() called at line 672:
    UMLClassifier *umlc = this->classifier();
which expands to 
    return dynamic_cast<UMLClassifier*>(m_umlObject);

Stackoverflow mentioned several reasons for crashing dynamic cast here http://stackoverflow.com/questions/278429/what-could-cause-a-dynamic-cast-to-crash. 

The most common reason for such issues is that the related m_umlObject has been destroyed, which we can catch with QPointer.
Comment 5 Ralf Habacker 2016-08-30 07:42:37 UTC 
Git commit 793ca536f67b59bed882f280ec7c9bcd1fffdb4f by Ralf Habacker.
Committed on 30/08/2016 at 07:42.
Pushed by habacker into branch 'Applications/16.08'.

Fix 'umbrello stopped working to the open a file try open another'.

There is still room for improvements in the case where the result from
dynamic_cast is 0 and used unconditional.
