v2.2.27 Panic: file rfc822-parser.h: line 23 (rfc822_parser_deinit): assertion failed: (ctx->data <= ctx->end)
Hi Aki,
debian jessie backports has been moved to archive.debian.org and
initially I was unable to install dovecot-dbg because of that. But I've
managed to resolve that issue now.
This was the command I ran:
doveadm -D -f flow fetch imap.envelope mailbox crm-spam.2008.g
Backtrace follows.

Thanks Timo. Given the age of these dovecot packages, and this being on debian oldstable, what should we do next? I'm inclined to just delete the email in question and move on.
