nan in bogofilter stats

Recently I am seeing large numbers of false Ham results from my well-trained 
bogofilter.

The following is the output of a bogofilter scan of an obvious spam mail.

The Ham result seems to result from the "nan" values.

Where do these come from and how do I fix it?

Cheers and thanks,
Stephen Davies
