[Dovecot] Crash of 1.0rc7

[Bernhard Schmidt]

Hi,

I pasted the logs in #dovecot already, but maybe someone here has a
little bit more insight. I'm running dovecot cvs branch_1_0 from Sep.
16th. Dovecot is doing LDAP userdb/passdb and I'm using deliver for
local deliveries.

Today my users complained about not being able to login anymore. I
opened ssh to that box and found the following messages

[ couple of mail deliveries using dovecot ]

after that the daemon apparently quit and was restarted automatically. No
errors reoccured after that.

The box only has a few private users. xenU guest domain running a mix of 
amd64 Ubuntu dapper/edgy. This is the first problem I've seen in this setup.
