This prompted me to update my webkitgtk to 2.42.3, the latest stable
release, then I rebuilt Emacs from the latest commit on master.  But
invoking xwidget-webkit-browse-url stills makes Emacs crash for me.

I get the signal 10 message, but I think that's been emitted for some
time when invoking xwidget-webkit-browse-url and isn't related to the
crash.  I don't get the libEGL warnings, but I do get the following,
which I think I haven't seen previously and seems like it could be
related to the crash (which is perhaps then different from what I
reported in my OP of this bug):

(emacs-master:10722): GLib-CRITICAL **: 15:46:25.356: Source ID 658 was not found when attempting to remove it
X protocol error: GLXBadWindow on protocol request 151
Serial no: 6143
Failing resource ID (if any): 0x2e001fe
Minor code: 32
This is a bug!  Please report this to bug-gnu-emacs <at> gnu.org!
