I just tested with census_wake2000 from the NC demo dataset and can 
confirm the issue.

The problem seems to be with the type 'area' which is not recognised 
somewhere along the process. Adding the option 'centroid' to the 'type' 
parameter and using that option makes it create the expected labels.

Could you file a bug about this ?

I'm not sure which would be the better solution:

- Leave the options as is and change the code so that 'area' is remapped 
to 'centroid'

- Change the options from area to centroid.
