Date: Mon, 20 Mar 2017 01:59:24 +0100

The steps I do to reproduce the bug are:
>$ emacs -Q
Then in emacs:
  M-x xwidgets-browse-url RET http://www.google.com RET
Emacs crashes and I get this error:

Thanks.

Can you try the latest release candidate of Emacs 25.2?  This problem
might be fixed there.

A reddit user suggested[1] this is fixed now (possibly due change of
webkit version used); do you see this in 26.1?
