[postgis-users] still problems with Mapserver and MULTIPOLYGON layer

hi all,

after installing PostGIS-1.3.5 (GEOS-3.0.0) in a PostgreSQL-8.3.6
server instance I tried to 
access on a MULTIPOLYGON Dataset using Mapserver 5.2.1.
First everything seemed to work fine, but sometimes Mapserver crashed
with an internal Server error.
PostgreSQL Server logs only this small notice:
'LOG:  unexpected EOF on client connection'

After that I checked the features and found out, that only a few
geomtries produce this error.
one Example:
the simple geometry

MULTILINESTRING((4508495.77831567 5996070.27480638,4508510.9569937

5996297.72341308,4508629.21044457 5996307.72555058))

requested with this boundingbox ends in a Mapserver crash :


The crazy thing is, if you move the BBOX a little more to the right or
left, everything goes right.
It seems to me this is a  problem similar to the bug actually resolved
in PostGIS-1.3.5 ?!
Is there anybody who can reproduce or prove this behaviour ?
