 Plugins like BuddyPress and bbPress use get_the_author_meta() on posts in
 loops that may not set the $post global or might not even be a post at
 all. Things like shortcodes and secondary loops of posts with their own
 WP_Query object still need to use get_the_author_meta() and might not have
 user ID information available in the $authordata global.

 I suggest a few sanity checks to check for object/array values, and
 load/reset them if they aren't around. Long term we should look into
 smoother ways to get possibly cached post author data directly.

 BackPress, bbPress 1.x, and !WordPress pre 2.8 had functions like
 get_the_author_id() for convenience sake, but they were all deprecated in
 !WordPress 2.8 in favor of the singular author_meta function.
