Issue with deformation motion blur

[jasperges]

(This is on OSX, I wasn't able to test it on other platforms yet.)
When I enable 'deformation motion blur', the exporting goes fine, but Appleseed gives the following error for the object which has the 'deformation blur':
failed to load mesh file Cube_deform.obj: i/o error.

If I open the .obj in Blender, it loads just fine. So I'm not sure what the problem is.
You can find a .blend which produced the error here: http://www.pasteall.org/blend/30400

Just committed a fix. It was an error of the mesh being written to the .appleseed file incorrectly (needed the relative parent "meshes" directory)

Thanks, works like a charm now!
