[Dovecot] Dsync Error Can't Delete Mailbox

Greetings,

I'm getting this error in the dsync logs:

Warning: Destination mailbox INBOX has been modified, need to recreate it before we can continue syncing dsync(foo@bar.org): Error: Can't delete mailbox INBOX: INBOX can't be deleted.

In this situation, what should I do to remedy the problem? Just delete the backup and rebuild?
