Preparing for replication: dsync-local(testaccount): Panic: file mbox-lock.c

I am preparing a bit for setting up replication. However when I manually 
try to dsync an account, the first time I execute this[1] command it 
seems to be ok. The 2nd time I am getting this error[2].
If I add -1 (one way syncing) the error disappears. Does this mean I 
will have problems with setting up replication between these two 
servers?

Preparing for replication: dsync-local(testaccount): Panic: file mbox-lock.c

Maybe a bug? 
I deleted the whole tree on the destination server, ran 
doveadm sync -D -1 -n inbox -u testacc tcp:mailxx.local:542
Only the directory structure of mdbox was created, no files.

2nd time I run:
doveadm sync -D -1 -n inbox -u testacc tcp:mailxx.local:542

The files are created in storage. 

What makes the m.XXX reset? I thought this would start at m.001 
after deleting the whole home dir

Replication is not supported with mbox format. You can only do 
unidirectional sync out of mbox.
