Bug: V6 paste object from other file brings in too many materials

I have a V6 file from which I copied a single object (that used to be part of a group) and then opened another file and pasted it in, upon which all materials from the previous file also was added. So not only the one material that was assigned to the coped file. So this seems like a copy-to-clipboard-issue. There were multiple materials with images assigned to them.

(Sorry, can not share the file)

Hi Jorgen - so far I cannot make this happen from scratch - if you encounter this on a file that you can share, please send it along.
