"Call to member function" errors

Hi,

I'm running the latest version of Gallery from CVS (as of 12:30 BAT on 21/08/04).

I'm seeing the following problems.

When trying to delete an album:
Fatal error: Call to a member function on a non-object in /var/www/robinbowes.com/gallery/main-CVS/delete_photo.php on line 28

When trying to sort the photos in the same album:
Error: no album specified

When trying to change the owner of a photo in the same album:
Fatal error: Call to a member function on a non-object in /var/www/robinbowes.com/gallery/main-CVS/photo_owner.php on line 42

Any ideas what might be causing this?

R.
