I'm trying to convert from an old Dovecot (1.0.15) and mbox to a new Dovecot and maildir. I'm running into several problems with dsync which are causing my mboxes not to convert.
If I use LAYOUT=fs (as I'd prefer) I get an error because I have a
mailbox called "subscriptions", and none of my messages convert. Is
there a way to get dovecot to put its own metadata in dotfiles instead?
(I guess I can rename my mailbox too :-)
% dsync mirror mbox:~/Mail dsync(nriley): Error: read() failed with subscription file /home/nriley/Maildir/subscriptions: Is a directory dsync(nriley): Error: Can't update subscription +/INBOX: Internal error occurred. Refer to server log for more information. [2010-10-21 20:17:55] [...]
Also, what "server log" is it referring to above?
So I tried without LAYOUT=fs, and dsync successfully converts some mailboxes, then crashes:

I tried running it in GDB but that crashed GDB, so hopefully the above info is OK...

I'm using the Debian packages from rename-it.nl. Here is doveconf -n output:
