Report to https://bugs.kde.org

Reproducible: Always

Steps to Reproduce:
1. Open umbrello.
2. In Tree View, right click on "Logical View" node.
3. In popup menu, hover over "New" item.
4. In secondary popup menu, left click "Class". Accept given name "new_class".
5. In Tree View, under node "Logical View", right click node "new_class".
6. In popup menu, left click "Copy".

Actual Results:  
Umbrello crashes.


Expected Results:  
Class information is copied to clipboard, so it can be pasted into Tree View or Class diagram.
