            Bug ID: 345388
           Summary: Dangling pointer issue on document close
           Product: umbrello
           Version: Git
          Platform: Other
                OS: other
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: umbrello-devel at kde.org
          Reporter: ralf.habacker at freenet.de

In UMLPackage::removeAllObjects() there is the following code fragment 
...
        removeObject(o);
        //delete o;
        // CHECK: Direct usage of the destructor crashes on associations.
        o->deleteLater();

While doing a research related to bug 73847 I stumpled over this comment. 
Uncommenting the code fragment  to
        delete o;
        // CHECK: Direct usage of the destructor crashes on associations.
        //o->deleteLater();

still let umbrello crash on document close because of accessing  a dangling
pointer. 

Reproducible: Always

Steps to Reproduce:
1. change code mentioned above
2. compile umbrello
3. start umbrello 
4. click on "new document"

Actual Results:  
umbrello crashes

Expected Results:  
umbrello should not crash
