Comment (by kovshenin):

 I think r32717 will break column headers for all plugins that explicitly
 set `$_column_headers`, because up until r32644 only three items were
 expected from `get_column_info()`, but now we check for at least four and
 skip the explicitly set headers entirely if that's not the case.

 [attachment:25408.20.diff] makes sure the function passes an array of at
 least four items, with null as primary. Too many arrays? You bet.
