[Regression] Writer can't insert a table of contents in Yakkety

[Simon Quigley]

I attempted to insert a table of contents in LibreOffice Writer, but instead of inserting it properly, the program freezes. I am running Yakkety, so I set up a Xenial LXC container to see if I could reproduce with that version. I SSHed into the LXC container with X forwarding, set up folder sharing between my host system and the container to confirm that it's not the file that's the problem, and launched LibreOffice Writer. I could successfully create a table of contents. So this a regression from the version in Xenial.
