Immediate after connecting? Or after some command? Anyway, no, I can't reproduce it. dovecot -n might help.

So here's all I have, with what Postfix sees upon delivery:

Crashes when the lmtp process has delivered the first message and receives the LHLO in the 2nd connection for the 2nd message. Backtrace is attached.

http://hg.dovecot.org/dovecot-2.0/rev/b791ebb2c700 should fix it.

Looks fine with latest changeset: 11016. Thanks Timo :)
