#1252: SRID appearing in ST_AsText for particular multipolygon

Comment(by robe):
ahah -- I was able to remutate it outside of my database by running these.
So not sure if the issue is with ST_Dump or ST_Union except it seems to be
fine in my PostGIS 2.0 database, but spits out this thing in my 1.5. Both
are running GEOS 3.3.1
See attached table and query
{{{
-- no weirdness --
SELECT ST_AsText(geom) from weird_mpoly;
--it mutates into something scary --
SELECT ST_AsText(ST_Union(geom))
FROM (SELECT (ST_Dump(geom)).geom
FROM weird_mpoly) As foo ;
}}}
Strk -- remember that problem I was talking about and how it crashed my
server and I couldn't figure out which set of data I was processing. I
wonder if something like this was happening. This geometry is generated
from the same process that caused the crashing I mentioned in ticket.
