This is a GTK bug, that gtklabel didn't set pango attributes when calling gtk_label_set_pattern, only effective_attrs is set. To provide a workaround on adding underline to specified text string, please call gtk_label_set_attributes with customized PangoAttributes.
I would suggest this bug priority as low since we have an alternative way to add underline.
