Re: controlling icon order

Is there a more GIO-specific forum for this discussion?

I disagree.  GIO is explicitly adding the generic fallbacks which exist 
in the gnome theme.

Agreed.

From the icon theme specification:
In order to have a place for third party applications to install their 
icons there should always exist a theme called "hicolor".

I think this is a good approach, from the caller's standpoint, though I 
don't know who takes responsibility.  Would GTK add an extra last-ditch 
parameter to the choose_icon API?  Or (shiver...) a tiered icon name 
list (gchar*[][])?

Thanks again for all of your help.  It's really helped me to understand 
my original problem (along with a pointer on the gnome IRC channel to 
look into GIO in the first place...).
