Textures not included when using "Export Selected" (Bug)

I’ve tried exporting parts of my models using “Export to” and using Collada as the format. I also check “Save texture”, but the texture folder is not included, nor does it seem packed into the .dae file.

This behaviour does not happen when I use “Save as” and chose Collada. This includes everything, including hidden layers though.

I’m running V5 R12 64bit, latest version.
