 All of a sudden I seem to be having weird environment problems with
 BuddyPress. I haven't figured that out yet, but whatever's going on, led
 to a nice fatal:

 There's a route through `bp_groups_prefetch_activity_object_data()` where
 `$uncached_ids` can be set to an empty array, and when it's used with the
 `wp_parse_id_list()` function, it returns an empty string, leading to the
 malformed SQL error as per this ticket description.

 I am getting this on the /groups/mygroup/ screen (i.e. activity view).
