I just found a problem in the Folders management in Basic View when you 
have many folders.

I have more than 100 old folders, most of them unsubscribed.
When I click "Show All" I get the full list. But when I clicked "Hide 
Unsubscribed" I got a blank page!
The server error log shows:

PHP Fatal error:  Maximum function nesting level of '100' reached, 
aborting! in /horde/imp/lib/Mailbox.php on line 280

and a long (100) stack trace, with many "IMP_Imap_Tree->next() 
/horde/imp/lib/Imap/Tree.php:2028"

Workaround: increase xdebug.max_nesting_level in the server's php.ini 
and restart the server. E.g

xdebug.max_nesting_level = 500
