The documentation says:

$ If the STRICT option is specified, the query must return exactly one
$ row or a run-time error will be reported

http://www.postgresql.org/docs/8.3/interactive/plpgsql-statements.html

In this case the query will always return one row.  The row may have a
NULL if no matching values were found, but the row will be there.

select max(x) from (select generate_series(1,10) as x) y where x > 10;
 max
-----

(1 row)

Not a bug.
