Actually, this is a real error. The subsets requested here will be inside the
image's bounds, so getSupportedSubset should return true, assuming subsets are
supported at all. It looks like they are not. (This can be fixed by not
including raw etc in the extensions listed in brd_supported, as Derek
suggested.)

(Also, FYI: \n is not needed here, since Error::Nonfatal takes care of
formatting for you.)

Done.
