[imp] Warning: array_keys(): The first argument should be an array in /var/www/localhost/htdocs/horde/imp/lib/Folder.php on line 91

[Rob Rosenfeld]

Upgraded to CVS Head today and get this error at the top of imp Inbox 
and Compose (at least), but not (at least) Folders pages:

Warning: array_keys(): The first argument should be an array in 
/var/www/localhost/htdocs/horde/imp/lib/Folder.php on line 91

I updated settings in setup.  The change_folders configboolean was 
removed in conf.xml in this update and I can't help notice the "folder" 
connection.
