Description Joris Steyn 2013-11-12 12:22:36 UTC 
Umbrello crashes in the cleanup-phase (application close or loading a different file) if the user pasted a class containing one or more attributes.



Reproducible: Always

Steps to Reproduce:
1. Create a new class in the Logical View
2. Add an attribute to the new class
3. Copy the class in the tree view
4. Paste the class in the tree view
5. Close Umbrello (or load another file)
Actual Results:  
A SIGSEGV is received and the crash handler kicks in.

Expected Results:  
The application should cleanup correctly and close without errors.

The memory violation occurs in the destructor of CodeClassField, relevant part of stack trace:

Application: Umbrello UML Modeller (umbrello), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
