Comment (by greuben):

 On trunk we cannot query without 'key' arg in meta_query(generates invalid
 sql)
 Lines 495-496
 {{{
 if ( empty( $meta_key ) && empty( $meta_value ) )
         continue;
 }}}

 One small bug there is $meta_value is always empty there.

 Regression introduced in [17699] and [17674]
