I'm guessing it's probably an unintended side effect of this line of code in
_hm_run_search() in Class::DBI::Relationship::HasMany:

    @search_args = %{ $search_args[0] } if ref $search_args[0] eq "HASH";

It's not clear to my why that line was added.

I recommend that you submit a bug report for this issue on
http://rt.cpan.org/NoAuth/Bugs.html?Dist=Class-DBI. You should attach a
failing test case (i.e., a patch to one of the t/*.t files in the
distribution) to your bug report if you want Tony to take quick action.

Hope this helps,
Ed
