Do you have a theme definition in /usr/local/share/icons/hicolor ? Probaby 
not, so when loading the icon from your theme (breeze, oxygen, whatever) that 
is most probably in /usr/share/icons/, why would the code fall back to a 
different "hicolor" theme?

I understand what you want but i don't think icon themes work like that.
