Append dont work?

Hello. I have append many times without any problem. But for the last months append items from other blendfils don’t work for me.
This time I try to import (Append) a pear of shoes to my latest project but nothing happen when I try. Why
I run on Blender 2.67b

There is about no objects named explicitly except some. Boots are still called Cube. Guess, MouthNose was only one i saw in Object section of file.
Ctrl click on some object in Outliner window and assign own name to it. Do this for all objects. Save file. Then, when append, you go to Object folder of file you append from and easily find needed part.
There is nothing broken in Append functionality; all works just fine.

Thank you eppo. Work fine.
