The docs for gtk_file_chooser_set_filename explain that if a file is new, we should call gtk_file_chooser_set_current_name instead. (But in that case it is necessary to set the directory separately.) Qt doesn't make a distinction between a save dialog for saving a new file vs. a dialog for re-saving an existing file, so it seems this is the better way to do it all the time, since a save dialog would most often be used for saving a new file.
