This also upgrade most other qt related packages * `.cabal-sandbox/bin/hdur` * I see a grey window with the subtext "foobar". When I press 'o', a black squiggly line appears on a white background. * No crash. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8406#comment:16 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
