MS does exactly that. Specifying a layer group in QUERY_LAYERS is
basically equivalent to specifying every layer corresponding to that
group.

Simply ommit that additional layer:

>   LAYER 
>     NAME "rt_cat.idcatbdfog"
>     TYPE POLYGON
>     METADATA
>      ....
>       "ows_include_items" "all"  
>     END
>     TEMPLATE 'void'  
>   END

> msShapefileOpen(): Unable to access file. No (NULL) filename provided.
> msBuildPath: Unable to access file. 
> msShapefileOpen(): Unable to access file. No (NULL) filename provided.
> msBuildPath: Unable to access file. 
> msBuildPath: Unable to access file. 

MS is somewhat confused and tries to query that layer which has no data.
