I've just enabled core dumps on the involved FreeBSD system. Let's see
if
it dumps something..

assertion failed: (srcleft <= CHARSET_MAX_PENDING_BUF_SIZE)

I got a core file this morning.

opening it with gdb I get this:

(gdb) core imap.core
Core was generated by `dovecot/imap'.
Program terminated with signal 6, Aborted.
#0  0x0000000011c1347a in ?? ()
(gdb) bt
#0  0x0000000011c1347a in ?? ()
#1  0x0000000011c13444 in ?? ()
#2  0x0000000000018dee in ?? ()
#3  0x306db139575f3b0d in ?? ()
#4  0x00007fffffffc144 in ?? ()
#5  0x0000000000000000 in ?? ()

Doesn't look clean at all.

let me know if I should upload the file somewhere.

Thanks

That is not that helpful. Did you install debug symbols for Dovecot? 
This is usually a separate package. It all depends on your OS. I am not 
familiar with FreeBSD.
