Comment 13 for bug 1847157

I'm a bit worried that the reporter from upstream seems no longer active in this bug. Looking at the changes, those seem like good memory-leak fixes (especially from upstream) so I have accepted them into -proposed.

As for releasing those into -updates, I'd prefer if we got an actual verification from upstream here. Christian, could we make this the acceptance criteria then? Would you be able to chase down some proper verification?
