I've recently updated from 7.0 to 7.1, but I now notice the IMAP subfolders do not show in IMP.
The dropdown list in IMP only displays "INBOX" and the MOVE|COPY dropdown only has "INBOX" and "New Folder".
If I click on Folders, I get the following messages in /var/log/messages:
 httpd: PHP Notice:  Undefined index:  a in /home/httpd/html/horde/lib/Horde/IMAP/Tree.php on line 1275

Can anyone shed some light on how to fix this?
I actually updated IMP from the sme repository separately before I did the full update, and noticed it wasn't working then.
Edit: Just for completeness, IMAP access via other clients (Thunderbird, Mulberry) is fine. Also, toggling the IMP setting to "subscribe to folders" doesn't change a thing.
