Horde/Imp problems

[Price,Neil]

I've set up a test Kolab 2.2 server using the native debian port.

I set up a test user using kolab-webadmin

I set up horde and activated imp

I can log into horde as that user but I get

Notice: Undefined index: % in /usr/share/horde3/imp/lib/IMAP/Tree.php on
line 1628

in the top left hand corner

If I look at that line of code its

return (($elt['a'] & IMPTREE_ELT_NEED_SORT) &&
(count($this->_parent[$elt['v']]) > 1));

My log file says this:

Any ideas? If I activate Kronolith I get more errors.
