Have you created the dbox directory before running dsync? And opened it
with some tool? I tried with your config and it worked fine.

The reason why these duplicate INBOXes happen is when INBOX exists both
in source and in destination when dsync is run. Typically this means
that you've created the destination INBOX already by e.g. logging in or
delivering a mail there or something..
