[Dovecot] problem with test56

Hi all, im doing some tests with the test56 release and im seeing some problems with APPEND (may be related to something else, I just see it with APPEND).

When I ask someone to move some emails from one mailbox to another, after some messages (seemingly random), the client experiences a 'hang'. When tracing the process what seems to happen is that dovecot doesnt send a final OK after that specific email. It's kinda hard to attach a gdb at that point, so for now, maybe someone has seen this also?
