Ah, of course, I didn't anticipate that. I think it would have always
happened, but previously, return values for add/removePath didn't
exist though, so they weren't checked of course.
I think it's probably safe enough to just stop checking removePath's
return value in QVERIFY there (plus a comment, noting this issue).
I'd expect the behaviour, I just didn't think of it when adding
checking of add/removepath calls...
