Thanks for the report--but clabel is intended to be used only with 
contour, not with contourf.  Typically one would call contourf, and then 
call contour, perhaps with a subset of the levels used in contourf.  The 
ContourSet resulting from the contour call would then be used in the 
call to clabel.  Example:

http://matplotlib.org/examples/pylab_examples/contourf_demo.html

In this example the contour lines are black, but if you don't want the 
lines to show up at all, you could make them transparent, and then 
include a "colors" kwarg in the clabel call.
