Can you summary(the_geom) ?
Summary() returns the structure of the geometry, including
BBOX and SRID presence in inner components, I suspect
a SRID or BBOX inside them. Please try that, and provide
an EWKB of it so I can make further tests and eventually
provide a geometry_cleanup() function for these cases.
