--- Operating System, Graphics card ---
Ubuntu 12.10 GeForce GTX 260

--- Blender version with error, and version that worked ---
tested on official build 2.67 and r56534

--- Short description of error ---
Can't use "from dupli" method on particles with object type of visualization, then scene linked to other.
I think, it because texture coordinates lost.
In images you can see
1. cubes in original file - colored by gradient, using uv-layer of sphere.
cubes in new file, linked from first scene - solid gray, no UV-layer (if texture is lost they must have diffuse color).

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

I create a simple scene to reproduce the error. cubes duplicates on sphere, by particles. Gradient texture set color of cubes, using "from dupli". This objects are grouped in lib.blend and linked to test.blend
1) open lib.blend and render - You will see, that cubes have different colors
2) open test.blend and render - now all cubes sold
