With the list copied this time :-) :-) Email is hard. CRS is easy

Jochen, (reposting & stripping stuff to remain below the 60 kB limit of 
the mailing list)

I just looked at your shapefiles. The issue is not with the CRS. It is 
with the actual geometry coordinates. They are all in the [0,1000] x 
[0,1000] range, which is totally outside of the area of validity of the 
CRS (the false easting / northing values of the CRS are 400,000, so when 
close to 0, you're 400 km off the center of the projection). So 
displaying it offboard of France is the *right* thing to do. There must 
be have some processing done at some point on your original shapefiles 
to alter their coordinates and normalize them to [0,1000].
