Nautilus ignores hidden files in properties metadata

[Lanoxx <lanoxx gmx net>]

Hi,

I was copying and synchronizing some folders today and suddenly 
realized, that when I right click on a folder and look at its 
Properties, if the folder contains nothing but hidden directories then 
its Contents are shown as "nothing" I would have expected to read as "1 
hidden item(s), xyz kB".

As a result I might have deleted a couple of folders that still 
contained hidden files. Is this a known bug or even a feature?

Disclaimer: Im running Ubuntu which ships Nautilus 3.4.2 so it might 
have been fixed in 3.6.

Kind regards
Lanoxx
