[postgis-users] NOTICE: IllegalArgumentException: point array must contain 0 or >1 elements, ERROR: Exception in LWGEOM2GEOS

[Daniel Degasperi]

|*Hi,
I have some problems with a MultiLinestring imported with *||*shp2pgsql.

If I try to check it's validity (or try to do anything else on it)*||*:

SELECT 
isvalid('0105000020E0670000010000000102000020E06700000100000016DA52BA62A04141FFF3AD290B735241');

*||*I get the Exception in my e-mail subject.

How can I check the geometry, if already isvalid chokes. I could only 
select NumPoints(the_geom) and compare it to the allowed range of the 
geometry type (e.g. 0 or > 1 for MULTILINESTRINGS).

Can this be considered to be a bug of PostGIS/GEOS?

Software stack:
CentOS 5.4, 64 bit
PostgreSQL 8.2.14 (from CentOS Testing)
PostGIS 1.4.1
GEOS: 3.1.1

*||*Best regards
Daniel
