[Dovecot] v1.1.beta11 deliver crashes when quota exceeded

[arvids]

Hello,

v1.1.beta11 deliver crashes when quota exceeded. This also reveals another 
problem in v1.1.beta11 - imap process does not follow quota settings - this 
user copied(with imap client) to his imap folder large volume of emails  and 
these emails significantly exceeded quota settings for this user, but imap 
process did not complain about it.

Here is full backtrace of deliver crash:
