This report resembles a message Emilia posted in postgis-users a
couple of weeks ago.  The only public discussion is a request for
the PostGIS version and copy of the data:

Emilia, did you and Sandro (strk) have off-list discussion about
this problem?  What do version() and postgis_full_version() return?
What happens if you select the geometry column without a join, i.e.,
"SELECT the_geom FROM wwf_terr_ecos_multigeom WHERE ..."?  Do you
get the segmentation fault with the original query if you select
AsText(the_geom) or AsEWKT(the_geom) instead of just the_geom?

Did the segmentation fault leave a core dump in your $PGDATA directory
or somewhere beneath it?  If not then you might need to adjust your
coredumpsize resource limit.
