Some recent change (probably in libertine) caused this test to start failing on my system because the `` wasn't being combined properly into a double open quotes (being instead, interpreted as two single open quotes). Since the test wasn't using the repository standard font, I simply switched to using that font instead of trying to figure out the exact nature of the problem. The result does the double open quotes properly, but also has significant other changes to the font (which is to be expected).
