I happened to catch this one today, in the course of testing folder names 
with non-alphanumeric characters.  Here's how I can reproduce it with IMP 
CVS RELENG_3:

 - Create a folder with curly braces in the name (I used "b {c} d" and 
created it manually outside of IMP).

 - From the INBOX, choose the "Folders" button at the top.

 - The IMP frame will display:

Warning: Undefined offset: -1 in /var/www/html/horde/imp/lib/Tree.php on 
line 320
Warning: Undefined offset: -1 in /var/www/html/horde/imp/lib/Tree.php on 
line 320
Warning: Undefined offset: -1 in /var/www/html/horde/imp/lib/Tree.php on 
line 320
Warning: Undefined index: name in /var/www/html/horde/imp/lib/Tree.php on 
line 652
Warning: Undefined variable: lastid in 
/var/www/html/horde/imp/lib/Tree.php on line 657
Warning: Undefined index: in /var/www/html/horde/imp/lib/Tree.php on line 
657
Warning: Undefined variable: lastid in 
/var/www/html/horde/imp/lib/Tree.php on line 663

 - Pressing browser's "Back" will get you to the folder list.  But
clicking the "folder refresh circle-arrows" icon will get you the Tree.php
warnings again.

I can see where this is heading (presumably this is interfering with 
c-client specifications like "{imap.example.com}INBOX").  Does the IMAP 
specification say that braces are not legal characters?  5.1.3 seems to 
imply that & is the only special one, I just learned today.  :-)
