Array#- does not remove an element of type hash (line 8):
irb(main):001:0> a = {}
=> {}
irb(main):002:0> b = {}
=> {}
irb(main):003:0> c = []
=> []
irb(main):004:0> a == b
=> true
irb(main):005:0> c << a
=> [{}]
irb(main):006:0> c.index(a)
=> 0
irb(main):007:0> c.index(b)
=> 0
irb(main):008:0> c - [b]
=> [{}]
irb(main):009:0> c - [a]
=> []

Looks like both of these issues were fixed a while ago in ruby_1_8 and in ruby_1_9.

You might wanna close this ticket but Kirk Haines should be informed so he can backport it to 1.8.6 (in case it's not there yet).
