[Dovecot] recent dovecot: assertion failed.

[Mario Nigrovic-rvvk40]

Sounds similar to a problem I was having.  imapd is core dumping.
This issue was largely fixed under beta9 (the core dumps certainly were).

You can find other patches suggested by Timo under the "uidlist files are gone" thread (very recent).
