It isn't meant to. The BrowsePoll and Browsing(send) support is for
legacy sites, and Browsing(recv) is a stop-gap until all the dialogs use
cupsEnumDests() or the equivalent. For GTK+, it uses its own
implementation (as cupsEnumDests is blocking -- Mike, please stop
writing blocking interfaces ;-) ). For Qt, I've written a patch to use
