Comment (by strk):

 The bug seems to be fully inside ST_BuildArea, either it's a but there OR
 the edges are not properly noded according to GEOS:

 {{{
 strk at strk=# select st_area(st_buildarea(st_collect(geom))) from
 t6129_outer_ring_edges;
  st_area
 ---------

 (1 row)

 strk at strk=# select st_area(st_buildarea(st_union(geom))) from
 t6129_outer_ring_edges;
         st_area
 ------------------------
  0.00030558393262683487
 (1 row)
 }}}

 The t6129_outer_ring_edges table is created by t6129_outer_ring_edges.sql
 just attached
