Cannot Access the Folder Permissions Menu within the UI

Hi all,

Have installed the 7.x .dev version, and can create a new folder within the UI using the admin account. However, when I try to edit the folder permissions the screen greys out and hangs.

I checked the error logs and got the following message:

http://www.mydomain .com/?q=filedepot_ajax/getfolderperms

Notice: Undefined variable: role_perm_records in template_preprocess_filedepot_folderperms_ogenabled() (line 780 of /home2/mydomain/public_html/modules/filedepot/lib-theme.php).

I'm confident that I have missed something obvious in the installation and setup phase, but I've double and triple checked and I cannot work out what!!!!

I am also getting the same problem with the user_perm_records at line 750.

Hoping somebody can help.
