--- Operating System, Graphics card ---

Windows XP/7


--- Blender version with error, and version that worked ---

error in v 2.68a
worked in 2.64


--- Short description of error ---

You can export a mesh as COLLADA file with normal map.
The effect is correctly set with <bump> tag of the extra profile FCOLLADA .

But when you import this file, the normal map is not bound to the material ( the image is well loaded ).


--- Steps for others to reproduce the error (preferably based on attached .blend file) ---

You can reproduce this with the attached .blend file . It contains a simple cube with color and normal maps.
