Actually I think this is exactly the correct behaviour from Dovecot. 
The command that produced this was:

1 RENAME test test.test1.test

So Dovecot moves test and everything under it to test.test1.test. There 
is no requirement in IMAP that "test" or "test1" has to exist.

However, I think it could be possible to get Dovecot into infinite loop 
with this. I'll have to check.

Maybe Dovecot should just disallow this though. Especially if it's not 
simple to fix the looping problem..
