 hp2ps reports `integer unexpected` when run on a profile file created with
 HEAD. The profile file contains entries such as the following:

 {{{
 $ grep System.Random Test.hp
 9Kgekc9yEaLHLNUuw6paWL:System.Random.StdGen     24
 9Kgekc9yEaLHLNUuw6paWL:System.Random.StdGen     24
 9Kgekc9yEaLHLNUuw6paWL:System.Random.StdGen     24
 9Kgekc9yEaLHLNUuw6paWL:System.Random.StdGen     24
 }}}


 To reproduce, first install random (there might be a simpler way, but this
 one is required to run `make TEST=concprog002 WAY=threaded2_hT`, which is
 failing at the moment):

 {{{
 $ cabal install random==1.1 --with-ghc=ghc-7.11.20150711 -v0
 }}}

 Note the package key for random starts with a number:

 {{{
 $ ghc-pkg --package-db=.ghc/x86_64-linux-7.11.20150711/package.conf.d/
 describe random | grep key
 key: 9Kgekc9yEaLHLNUuw6paWL
 }}}

 Then create a heap profile for the following program with `-hT`, and try
 to run `hp2ps` on it:

 {{{
 $ cat Test.hs
 import System.Random
 main = sequence $ replicate 1000 (randomIO :: IO Int)

 $ ghc-7.11.20150711 Test.hs -rtsopts -fforce-recomp -v0

 $ ./Test +RTS -hT -i0.001

 $ hp2ps Test.hp
 hp2ps: Test.hp, line 12: integer unexpected
 }}}

 Note that in the profile file the entries for libraries like `base`, `ghc-
 prim` and `integer-gmp` don't contain package keys (maybe the entries for
 random shouldn't either?):
 {{{
  base:Data.Dynamic.Dynamic       24
  integer-gmp:GHC.Integer.Type.Jp#        16
  ghc-prim:GHC.Types.:    24
 }}}
