Comment (by pramsey):

 So the problem seems to be with an empty input:
 {{{
 postgis25=# select st_removerepeatedpoints(st_snaptogrid('multipolygon(((1
 1, 1 2, 2 2,1 1)))'::geometry, 10));
 ERROR:  Unknown geometry type: 40 - Invalid type
 postgis25=# select st_removerepeatedpoints('multipolygon(((1 1, 1 2, 2 2,1
 1)))'::geometry);
 st_removerepeatedpoints
 ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

 (1 row)

 postgis25=# select st_astext(st_snaptogrid('multipolygon(((1 1, 1 2, 2 2,1
 1)))'::geometry, 10));
      st_astext
 --------------------
  MULTIPOLYGON EMPTY

 }}}
