Stephan, 

I looked through mapogr.cpp and there is no obvios reasons
why shapeObj's read through OGR would not have their
bounds set properly.  When you say that the extents
are set fine with shapefiles or PostGIS do you mean accessing
the shapefiles or PostGIS through OGR or using the direct support
for these types in MapServer? 

I would suggest that you submit a bug report via bugzilla
including the a sample data file, and a minimal script demonstrating
your problem. 

Best regards,
