pytest --fixtures-per-test -> 'DoctestItem' object has no attribute '_fixtureinfo'

[obestwalter]

Hi, I just stumbled over this behaviour when calling 'pytest --fixtures-per-test' in the pytest repo with a fresh venv on 3.6:

pytest --fixtures-per-test

[...]
-------------------------------------------------------- fixtures used by test_source_of_class_at_eof_without_newline --------------------------------------------------------
--------------------------------------------------------------------- (testing/code/test_source.py:395) ----------------------------------------------------------------------
tmpdir
    Return a temporary directory path object
    which is unique to each test function invocation,
    created as a sub directory of the base temporary
    directory.  The returned object is a `py.path.local`_
    path object.
tmpdir_factory
    Return a TempdirFactory instance for the test session.

It's reproducible with pytest 3.2.2 and develop install from master.
