Subject: Equality question

I am trying to use complex values as hash keys (they are actually method
calls caught by method_missing). However strange things are happening. Can
someone explain what's happening here please where marked?

confs = {"default" => "! Config\nfoo=bar\n"}
hash = {
        [:firmware_id] => "12.4.8",
        [:uptime] => 0,
        [:read_configs] => confs,
        [:defuzz_configs, confs] => {"default" => "foo=bar\n"},
        [:defuzz_configs, {"conf"=>"foo.txt"}] => {"default" => "foo=bar\n"},
}
p hash.size

key1 = [:defuzz_configs, confs]
p hash[key1]    # this works

key2 = [:defuzz_configs, {"conf"=>"foo.txt"}]
p hash[key2]    # this prints nil ??                  <<<<<<<<<<<


o1 = [:defuzz_configs, {"conf"=>"foo.txt"}]
o2 = [:defuzz_configs, {"conf"=>"foo.txt"}]
p o1 == o2              # prints true
p o1.hash == o2.hash    # prints false ??             <<<<<<<<<<<

Thanks!

Brian.
