Comment 6 for bug 1752453

Lubuntu's i386 testcases were all covered, so I tried MATE's instead. It passes with flying colors. In some ways, looks better than ours too!

Tested: http://cdimage.ubuntu.com/ubuntu-mate/xenial/daily-live/20180228/xenial-desktop-i386.iso.zsync

So this seems to be our problem alone.
