Confirmed. There is clearly a bug here. Thanks for pointing this out
and especially for distilling it down to a simple test case.

I don't think that's the right solution, because watch_bound_objects
gets copied around a bit, and would then disconnect too early. I'm
revisiting this code now to try to isolate the bug.
