[Dovecot] Panic: IMAP(...): Trying to close mailbox INBOX with open transactions

[Mike Abbott]

I have been seeing this crash, which has been reported before but  
apparently not yet resolved.  As with the previous reporters, I do not  
know how to reproduce it reliably.

Dovecot version: 1.1.rc5
Operating system: Mac OS X 10.5.2
CPU architecture: x86
File system: HFS+
Activity:  From the backtrace it appears the client logged out while  
in the middle of some operation.
