dovecot panic

[tobisworld at gmail.com]

Sorry to reply to myself ;-) but I found a way around this panic.

After unsubscribe and subscribe again to my inbox folder the panics in
maillog suddenly stopped. Before I got the panic on EVERY click on my
inbox in MUA.
I was cleaning up my mailbox (moved and deleted a log of messages) when
the error first occured today. Maybe related to that?

Anyway problem "solved" for me although I think that "something" on the
client should not be able to trigger such an error on server ;-) 

Cheers and have a good one
