Re: gtk_print_operation_run hang

Ok some new information. There is an incompatibility with g_idle_add and printing. I'm using g_idle_add for my own callback elsewhere in the application, and if I comment that out the printing starts working. What I think is happening is that the call to: priv->print_pages_idle_id = gdk_threads_ad
