No Haddock instance documentation

[Omari Norman <omari@smileystation.com>]

My Haddock documentation on squeeze doesn't have documentation for any
class instances. This is true both for the docs that come with Debian
and for the docs I build for my own packages. Other docs on the Internet
have instance documentation, even for relatively old GHC releases like
6.6.1:

http://www.haskell.org/ghc/docs/6.6.1/html/libraries/base/Prelude.html

I got a newer haddock from Hackage and it generated instance
documentation for my own packages. Is there a Debian bug here? Thanks.
