[Dovecot] imap dumps core when connecting with mutt

Hello,

I'm trying to investigate a problem with dovecot/imap dumping core when connecting connecting mith mutt (everything else works).

imap(user@domain): Fatal: master: service(imap): child 31752 killed with signal 11 (core dumped)

I managed to create a core file and passed that to gdb. The log is here [1].

I hope this helps - please tell me what else would be needed if not.

Thanks.
