[Dovecot] dovecot 1.1beta2 and dovecot-sieve 1.1.2 - crash in LDA

[Bernhard Schmidt]

Hi,

I've upgraded to dovecot 1.1beta2 and the latest dovecot-sieve release
yesterday and have one single mail that cannot be delivered repeatedly.

Log (reformatted):

All other mails work fine, so there is probably something corner case
here.

Timo, I'll send you the mail in private.
