Okay, that one was fixed upstream in
https://bugzilla.mozilla.org/show_bug.cgi?id=1257055

Can you try applying the patch there and see how things go from there?
(I'd rather avoid doing multiple uploads if it turns out not to be
sufficient, which I suspect might be the case).

Bumping severity because this pretty much makes the package unusable on
a release architecture.
