Perspective - Unexpected problem unregistering listener from session event bus

I had this same issue, with a binding that had multiple references to the same tag. Reorganizing the binding expression to only reference the tag once seemed to have made the problem go away.

Seems it happends when you reference a tag multiple times in one expression
