[imp] Error messages in listing folders

[robert sand]

Here is something that doesn't seem to cause a problem except that there are a 
number of these messages that come up when listing folders when going to 
subscribe to imap folders.

Warning: Undefined index: attributes in 
/var/www/html/horde-2.1/imp-3.1/lib/Tree.php on line 720

Warning: Undefined index: next in /var/www/html/horde-2.1/imp-3.1/lib/Tree.php 
on line 684

Warning: Undefined index: level in /var/www/html/horde-2.1/imp-3.1/lib/Tree.php

Does anybody know what I can do to make these go away or fix them?
