[Dovecot] imap crashed: (imap) killed with signal 11 in dovecot 1.2.5

[Robert Gabriel]

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:
