The fix in the link (http://askubuntu.com/a/851760/83302) worked for me as well on Xubuntu 16.04. Incidentally, someone on the Ubuntu-devel-discuss mailing list reported what I think is the same bug and workaround and suggested a more permanent fix: https://lists.ubuntu.com/archives/ubuntu-devel-discuss/2016-July/016779.html.
