I'm afraid I wasn't able to duplicate your error, unfortunately.
I was able to get the doubled Messages though, and I've filed that as
bug # 1068.
I wasn't able to completely duplicate your code, of course, and it has a
lot of moving parts - if you could simplfy it to a small code section
demonstrating the bug, that would be helpful in diagnosing the problem...

Another strange thing, my faces message is being duplicated (but i think that it probably my fault).
