Hi,
I just noticed a similar crash (well same assertion at least) on my
production server. No idea what the user did, but I know it's a normal
client, not some kind of script.
Since I don't know what the user did I can't reproduce the problem, but
I figured dropping a note won't hurt.
I'm running dovecot 2.2.11 on Arch Linux with ext4, config and
backtraces below.
PS: I'm not subscribed to the list, please make sure to CC me on replies.
Thanks,
Florian

backtrace from a core dump below, sadly it doesn't contain much
information since the dovecot build I'm running stripped.
