Cabal file parser can't handle colon in description
The description field of the cabal file in the haskell-mtl package currently in debian sid contains an url with a colon, which leads to this error:
ghc-pkg: 13: unrecognised field or section: "(<http://web.cecs.pdx.edu/~mpj/pubs/springschool.html>),"
This comes from Cabal.Distribution.ParseUtils
