Raster query gives error

[Spot]

Good morning list!

I have got a problem with raster queries. I use MapServer CGI on Windows
with jBox as viewer.
When I do a query by shape on a raster layer, MapServer throws the
following error:

mapserv(): Web application error. No way to generate a valid map extent
from selected shapes.

With a shape layer the query works without problems, meaning that the box
rectangle is given to MapServer properly.

Thanks for help,
Philip
