CVE-2018-16428

If something which looks like a closing tag is left unfinished, but
isn’t paired to an opening tag in the document, the error handling code
would do a null pointer dereference. Avoid that, at the cost of
introducing a new translatable error message.

Includes a test case, courtesy of pdknsk.
