I ran into this as well:

  parsec-ansi-wl-pprint roundtrip: FAIL (1.51s)
    *** Failed! Falsified (after 35 tests and 9 shrinks):
    Lst [App "\"\n\"" []]
    [" "]
    Lst [App "\" \"" []]
    Just [-" ", +" "]
    Use --quickcheck-replay=52162 to reproduce.
    Use -p '/parsec-ansi-wl-pprint roundtrip/' to rerun this test only.

I expect this is related to nick8325/quickcheck#359
