npe

Hi,

When building my maven site, I'm now getting a NPE. If I build the site again,
the site builds fine. If I maven clean first, and then build, the NPE comes
back.

The exception isn't being very informative about what may be wrong. In
particular, it's not giving me any hint about what file the problem was
encountered in. Any hints?

Matthew
