Hi,

I am migrating from 0.99.14 to 1.1.rc10 and from mbox to maildir.

During the conversion, via convert plugin, I get this assertion failure:

2008-06-13 14:12:54 Fatal: IMAP(username): Mailbox conversion failed, exiting

If it can be useful for debugging purpose, is there something I can do to
identify the mailbox causing the failure?

I am also investigating why the plugin tried to recreate directory for the
already converted mailbox "Ospedale".
