Does not make sense in the use-cases of that function, especially since we don't know whether it is actually due to an error, or some glitch (like an empty curve). Think we always want to get a mesh when using either operator conversion, or the `bpy.data.meshes.new_from_object` function. Note that an assert was also added to ensure we do try to convert from a valid 'geometry' object type.
