dovecot - Oct 2010 - bug in dsync

Hi,
I'm trying to convert mailboxes from mbox zu mdbox.
The following command was performed:

dsync mirror -u tsdauche mbox:~/.NCmail/Drafts
dsync(tsdauche): Fatal: execvp(-u) failed: No such file or directory
dsync(tsdauche): Panic: file dsync-worker-local.c: line 185 
(dsync_drop_extra_namespaces): assertion failed: (ns != NULL)
[1]   Abort trap (core dumped) dsync mirror -u tsdauche 
mbox:~/.NCmail/Drafts


I also tried other combinations with dsync, but they all fail... :(
I'm sending the core file and the conf output with this mail.
Hope you can find out whats the problem, thanks a lot!
Tobi

This is strange though. 

Anyway, with your config I get an error instead of the above crash:

dsync(tss): Fatal: All your namespaces have a location setting. It
should be empty (default mail_location) in the namespace to be
converted.
