[mapguide-users] problem with Ubuntu 7.10 + MGOS 2.0.1 + PostGIS

[Kenneth Skovhede, GEOGRAF A/S]

The "MgInvalidStreamHeader" usually comes out when the 
serialization/deserialization of objects fail.
Since Maestro does not use the serialization features of MapGuide at 
that point, it must be some
internal serialization that goes wrong.
