What is likely happening there is that you have a Style name attached
to a layer in your XML that does not exist or is misspelled:

(The behavior of the OGCServer is more strict that the standard
mapnik.load_map() in this regard)

In the <Layer> definitions, look for instances of:

<StyleName>stylename</StyleName>

and make sure they have corresponding:

<Style name="stylename">...</Style>

Feel free to file a trac ticket requesting this error be more verbose.
For example, it could output the actual name of the invalid style
encountered, to make finding it more easy.
