If the user has 0 mailboxes the following error appears when trying to  
open IMP:

Warning: array_keys() [function.array-keys]: The first argument should  
be an array in /srv/webmail.carnet.hr/www/imp/lib/IMAP/Tree.php on  
line 328

Warning: array_intersect() [function.array-intersect]: Argument #2 is  
not an array in /srv/webmail.carnet.hr/www/imp/lib/IMAP/Tree.php on

Warning: array_flip() [function.array-flip]: The argument should be an

Fatal error: Unsupported operand types in

This seems related to new code added in 1.2.7 and happens because  
$names array never gets initialized in case of 0 mailboxes. Patch is  
attached.
