Opencollada imports ignores normals ?

Hey.

I am importing opencollada files to Blender (v2.6) and evidently Blender ignores the normals that are provided and re-calculates them automatically.

Is that a bug ?
Is there something I should try to get the actual normals loaded correctly ?

I was referred to this forum after other (very experienced) Blender-users confirmed what I am seeing on some example files.
