Comment #10 on issue 492 by esteba...@gmail.com: Glamour browsers do not release all subscriptions to announcer objects http://code.google.com/p/moose-technology/issues/detail?id=492

I don't know why that test does not catch our problem. I presume that changing entities does not "fires" the presentation update mechanism who finalizes in a copy, I really don't know why :)
