glade and compiled resources

[iSage <isage dna gmail com>]

So, i know i can compile my resources and glade .ui file and load it using
builder.
However, i have a problem with icons.
Let's say a have a following structure:
/
window.ui
pixmaps/
             run-iso.png

And an button in .ui with icon_name = run-iso

Using gtk_icon_theme_add_resource_path i can tell where to look for my
custom icon, and it works.
But, how do i tell glade where to look for it?
interface-local-resource-path doesn't seem to work for themeable icons
