reactor tag causing NPE before post-processing

I am attempting to use the reactor tag, as in the Maven User Guide.  The 
following tag:

<maven:reactor
            basedir="${basedir}/projects"
            postProcessing="true"
            includes="*/project.xml"
            goals="site"
            banner="Generating Site"
            ignoreFailures="true"/>


Causes the following exception:

I  can't find any specific documentation on the reactor tag.  Can anyone 
see a reason why this exception is occuring?

Any help is appreciated.
