GtkD icon theme issue

[Benjamin Thaut]

I'm currently working with a file chooser. Whenever I open a folder that 
actually contains file I get the following error message:

Assertion file 'gtk' line 0: Could not find the icon 'gtk-file'. The 
'hicolor' theme
was not found either, perhaps you need to install it.
You can get a copy from:
	http://icon-theme.freedesktop.org/releases

Do I need a special version of these icon themes for windows, or will 
the normal version just work?  Is there something special I need to do 
for installation?

Kind Regards
