dovecot - Oct 2009 - imap crashed: (imap) killed with signal 11 in dovecot 1.2.5

Hi, I'm using dovecot 1.2.5 with mysql backend and seems in this new version
I have issues when loggin in, especially if there are mails in Inbox folder.

NOTE: version 1.2.4 worked perfectly and mysql was updated to version 5.0.86
from source code.

Here is my configuration and core dump:

Check the thread "Problem with dict-quota, deliver killed by delivery
attempt" from last tuesday (29 Sep) - and Timo's answer.

My dovecot 1.2.5 stopped crashing after applying this patch - which repairs
dovecot crashing when using quota other than Maildir++:
