Subject: String#% is not working on Ruby 1.8.7

To reproduce, I just copied the example right from ruby-doc
http://www.ruby-doc.org/core/classes/String.html#M001127 into irb
session.

>> "foo = %{foo}" % { :foo => 'bar' }
ArgumentError: malformed format string - %{
	from (irb):1:in `%'
	from (irb):1

I'm using
ruby 1.8.7 (2010-06-23 patchlevel 299) [x86_64-linux]
on Ubuntu amd64
