Comment 13 Kevin Wolf 2016-11-07 10:00:36 UTC 
Fixed with upstream commits 94d6a7a7 and aa2623d8. The first one does the actual
fix (by rewriting the code), but it doesn't build without the second commit.

Resetting the assignee as I can't change Fedora packages.
Comment 14 Cole Robinson 2016-12-13 01:28:55 UTC 
Fixed in the latest rawhide -rc3 build
