Umbrello crashes when an operation is added to a class that has already an operation with the same name, but different parameters.
How to reproduce: Create a new document. In "class diagram" add a new class, say "Test". Add a new operation named "op" and a parameter "int a". Add another operation named "op", too. Add to the new "op" the parameter "double b". Pressing OK (to add the new operation to the class) causes the crash.
