OS X 10.11, Libreoffice 5, can't save a document?

Greetings!

When I light up Libreoffice, everything seems to work just fine… Until I try to save the document.

That sends me to the beachball of death, then Libreoffice crashes.

I’ve removed ~/Library/Application Support/Libreoffice and re-installed the latest version of libreoffice, but I still have the issue.

I can’t even save a totally blank document of any type - 100% repeatable…

Any clues what might be going on here?

Thanks!
