Comment:

 If I change Gtk2hsSetup.hs from:

 {{{
 #!hs
 #if CABAL_VERSION_CHECK(1,10,0)
                                     installedPkgInfo pkg lbi inplace
 [packageDb]
 #else
                                     installedPkgInfo pkg lbi inplace
 packageDb
 #endif
 }}}

 to

 {{{
 #!hs
 #if CABAL_VERSION_CHECK(1,10,0)
                                     installedPkgInfo pkg lbi inplace
 (withPackageDB lbi)
 #else
                                     installedPkgInfo pkg lbi inplace
 packageDb
 #endif
 }}}

 It registers correctly.  The packageDb here is defined as:

 {{{
 #!hs
     packageDb = case flagToMaybe (regPackageDB regFlags) of
                     Just db -> db
                     Nothing -> registrationPackageDB (withPackageDB lbi)
 }}}

 In Distribution\Simple\Register.hs it has:
 {{{
 #!hs
     -- FIXME: there's really no guarantee this will work.
     -- registering into a totally different db stack can
     -- fail if dependencies cannot be satisfied.
     packageDbs = nub $ withPackageDB lbi
                     ++ maybeToList (flagToMaybe  (regPackageDB regFlags))
 }}}

 Anyway, it appears that the issue is with Gtk2HsSetup.hs and I will close
 this and add to a related ticket there
 (http://hackage.haskell.org/trac/gtk2hs/ticket/1203).
