Maybe I am doing something > stupid, again ;-) Not stupid at all; it just happens that clabel works only with contour, not with contourf. Clabel operates on the LineCollection generated by contour, but contourf generates a PolyCollection. It should be possible to call contourf, then contour, then clabel, and then make the LineCollection from contour invisible, but I don't have time now to come up with an example.
