Perhaps check that the line 
olayer.CreateGeomField(feat_defn.GetGeomFieldDefn(i)) is executed and its 
return code is 0.

Also, when running CreateLayer() with geom_type != wkbNone, this will create a 
default geometry field, which might get recreated again in your geometry field 
creation loop. But it does not look like like it is the case in your 
situation.
