panic: dsync and imapc

Hi Dovecot list!

I try to sync from a remote imap server to my local dovecot server via the dsync tool with imapc.

Here is my command:

# /usr/local/dovecot/bin/dsync -c /usr/local/dovecot/etc/dovecot/dovecot.conf -D -o imapc_user= test@example.com -o imapc_password=pwd backup -R -u test@example.com imapc:

Here the error message:

dsync(test@example.com): Panic: file quota-maildir.c: line 827: unreached

Please see the attached debug.txt for a full debug messages and stacktrace.

System info OS: Ubuntu 14.04 Server 64 Bit Dovecot: 2.2.13

Thanks,

Alex
