Stack trace

I can see that the Subject palette item is a "Component" intentionally (bug 312598 and bug 281977 ).

Adding Subject to a Use Case diagram causes the Metaclass selection dialog to open, _except_ when it is added to a Package, in which case it creates a Component.

Additionally, I found that clicking Cancel on the "Metaclass selection" causes an exception (full stack trace attached):
