Good find.
I think we should turn your case into a proper TAP test so that we can
incorporate it, for coverage -- the lines you patch do appear covered,
but obviously not in these specific conditions. I'm just not very sure
*where* to add it; maybe src/test/modules/test_extensions is the place
to have it, though that one doesn't have TAP tests currently. An easy
addition, though.
