Ah I recently hit this same error with GetLegendGraphic requests to a
MapServer WMS layer.  I used the Nabble search in the MapServer forum,
to read how this generic error is thrown for MapServer layers that are
in a GROUP.  There are tickets and discussions about that.  Anyway, not
sure if it is related to your issue, but you could also search the
archives to see what I mean.
