 In geodjango:

 {{{
 #!python
 from django.contrib.gis import geos
 g1 = geos.GEOSGeometry('MULTIPOLYGON(((0 0,0 10,10 10,10 0,0 0)))')
 g2 = geos.GEOSGeometry('POLYGON((1 1,1 2,2 2,2 1,1 1))')

 g1.contains(g2)
  => False

 g2.within(g1)
  => False
 }}}

 Both of the above should return True. The following combinations work fine
 though:
 polygon.contains(polygon)
 multipolygon.contains(multipolygon)
 polygon.contains(multipolygon)

 It's possible this has been fixed in a more recent version, though I
 couldn't find any existing tickets on it. Feel free to close if that's the
 case, stating when it was fixed.
