i remember there was also a hint about the application now needing to
"force" an icon on a button. (but cant seem to find the mail)

could someone point me to this/any document/info/example ?

im trying to do a play/pause button in glade3 (gtkbuilder), and i just
cant get any icons shown in a button any more... (nope, didn't get any
answer on this at glade mailing list)

cheers
