2006-05-15 Alexander Larsson <alexl@redhat.com> * gtk/gtk.symbols: * gtk/gtkprintbackend.[ch]: (_gtk_print_backend_create): Never unload print backends. Remove gtk_print_backend_unref_at_idle. * modules/printbackends/cups/gtkprintbackendcups.c: (cups_dispatch_watch_finalize): Don't use the unref_at_idle hack since that caused deadlocks. Instead we never unload print backends, which is not really a big problem.
