Hi,
   since we are in the middle of adding builder support, this would be a
great time to file a bug describing what would be the desired behavior
for builder (patches also welcome ;-) )

That being said, the rationale behind libglade style pixbufs is that
the pixbuf is either in the working directory, or in the specified pixbuf
directory (you can add a search path with the libglade api).

Glade 3 not allowing a full path is a shortcomming related to poor
handling of external resources (i.e. pixbufs related to a glade file
are tracked and copied with the glade file... poorly, also bug reports
and patches welcome...)

Cheers,
           -Tristan
