 Here are a couple of examples that probably should not behave like that.

 {{{
 >> NSUserDefaults.standardUserDefaults['oreilly.owned_books'] = [{:topic
 => 'macruby', :isbn => '9781449380373'}]
 => [{:topic=>"macruby", :isbn=>"9781449380373"}]
 >> NSUserDefaults.standardUserDefaults['oreilly.owned_books'].first[:isbn]
 => nil
 >>
 NSUserDefaults.standardUserDefaults['oreilly.owned_books'].first['isbn']
 => "9781449380373"
 }}}

 problem: The hash item defined by a key being a symbol is only available
 using a string key.

 {{{
 % macirb
 irb(main):001:0> { 'foo' => 'foo', :foo => :foo }
 => {"foo"=>"foo", :foo=>:foo}
 irb(main):002:0> h = _
 => {"foo"=>"foo", :foo=>:foo}
 irb(main):003:0> NSDictionary.dictionaryWithDictionary(h)
 => {"foo"=>"foo"}
 }}}

 Entries using a symbol or a string key should not be merged.

 During an offline discussion, Laurent said:
 Very likely a problem with the copy functionality of symbol.
