for the record the correct behaviour in this case should be
to return "(none)"

Comment 1 Jeff Johnson 2000-10-04 15:10:24 UTC
Returning an explicit "(none)" rather than an error message when querying an
unknown tag
using a legacy version of rpm would confuse two distinct problems
	1) rpm does not know about a tag.
	2) the tag does not exist.
which have different solutions (i.e. 1) is fixed by upgrading rpm, 2) is a
packaging or query option problem).
