Since this is query by example, if you want a list then you have to
ask for a list.  In this case:

my $query = [{ blah blah }];

I.e. just force the whole thing to be an anonymous listref.

I assume you're using my Metaweb.pm; the above should work fine for
it.  I need to work a bit on error messages from it, and make them a
bit more visible and perhaps Perl-appropriate.
