Jesse, can you still reproduce the crash? Also, what platform? Regardless, this shouldn't be an infinite recursion; it isn't in the shell...

Ah, so the infinite recursion is happening outside the engine when XPConnect tries to convert the cyclic object to nsISupports and the assert is bogus and can be removed. I added the assert for visual symmetry with the other Proxy functions but it clearly has false negatives.
