..OK, the mailbox no longer exists on disk. And if I try to delete it with
cyradm on the backend:

--clip--
i16.mappi.helsinki.fi> dm "DELETED.user.<censored>.BIOMEDICUM.Matkat 2012.06-20.Untitled Folder.4F17D602"
deletemailbox: System I/O error
--clip--

and the ghost mailbox doesn't go away.

If I run a reconstruct on the backend, I can get the mailbox to more or less
exist on the backend

--clip--
[root at pcn2 Matkat 2012]# ls
06-2012 ESHG
[root at pcn2 Matkat 2012]# sudo -u cyrus /usr/lib/cyrus-imapd/reconstruct -C /etc/imapd.conf.i16.replica -G "DELETED.user.<censored>.BIOMEDICUM.Matkat 2012.06-20.Untitled Folder.4F17D602"
DELETED.user.<censored>.BIOMEDICUM.Matkat 2012.06-20.Untitled Folder.4F17D602: failed to read index header

However, I cannot remove it, still, since Mupdate Master knows nothing about
it, still.

--clip--
i16.mappi.helsinki.fi> dm "DELETED.user.<censored>.BIOMEDICUM.Matkat 2012.06-20.Untitled Folder.4F17D602"
deletemailbox: the mupdate operation failed
i16.mappi.helsinki.fi> lm "DELETED.user.<censored>.BIOMEDICUM.Matkat 2012.06-20.Untitled Folder.4F17D602"
DELETED.user.<censored>.BIOMEDICUM.Matkat 2012.06-20.Untitled Folder.4F17D602 (\HasNoChildren)
i16.mappi.helsinki.fi>
--clip--

The replication problem did go away, though:

--clip--
[root at pcn2 ~]# sudo -u cyrus /usr/lib/cyrus-imapd/sync_client -vl -C /etc/imapd.conf.i16.master -u <censored>
USER <censored>
[root at pcn2 ~]#
--clip--

(which isn't that surprising, given that now the backend thinks the mailbox is
okay).

I did get the mailbox on the Mupdate Master using the normal ctl_mboxlist -m
command on the backend, and could remove it then. But I've still got no idea
how the ghost mailbox got there in the first place. Anyone else got anything
similar?
