Pairing role "Object style" with another causes additional empty style ( accumulated )

[Nils]

Notice: Accumulated into mega-topic.

Here, "Shape" is used as the second one.

@Nils ADDITIONAL:

This also happens when both, the canvas and the object have the same role ( only tested here with role "Object style" ).

EDIT:

Just tested, this happens with all roles, not just "Object style".

@Nils The first case is not a bug. The same object (with the same name) is used as a Shape style and as an Object Style.

The second one seems to be a bug. Added it to the backlog.

@vectoradmin Right, was doubting the validity of the second one aswell.
