Inconsistent cyradm/telnet mailbox description

    Hi !

    I moved some email accounts on a new server (Cyrus IMAP
2.2.13 on ubuntu 10.4). As a consequence, my mail client
(thunderbird) does not display (new) sub sub folders. The
funny part  is that if I create a new subsubfolder (INBOX.A.B)
then I can see any INBOX.A subfolders, even the eldest ones.

    I thought it was a thunderbird bug/feature (!?), but here is
what I get using telnet, then cyradm (DeptIMA & DeptTR both
have subfloders built with cm, the only difference is that I have
created a new DepTR subfolder with a mail client) :

root at albert:~# telnet albert 143
Connected to albert.
Escape character is '^]'.
* OK albert Cyrus IMAP4 v2.2.13-Debian-2.2.13-19 server ready
1 login "chaput" "passwd"
1 OK User logged in
2 lsub "" "INBOX.*"
* LSUB () "." "INBOX.Enseignements.DeptIMA"
* LSUB (\HasChildren) "." "INBOX.Enseignements.DeptTR"

2 OK Completed (0.000 secs 131 calls)
3 logout
* BYE LOGOUT received
3 OK Completed

root at albert:~# cyradm --user chaput albert
albert> lm
INBOX.Enseignements.DeptIMA (\HasChildren)
INBOX.Enseignements.DeptIMA.2eme_annee (\HasChildren)
INBOX.Enseignements.DeptTR (\HasChildren)
INBOX.Enseignements.DeptTR.1ere_annee (\HasChildren)

    ACLs, file properties, ... are the sames for DepTR and DepIMA.
And the problem is still there after a reboot, so there is no cache
side effect.

    Thank you for any hint !
