 Wrong type argument: number-or-marker-p, nil in window-edges
Date: Mon, 10 Dec 2018 11:05:27 +0100

You’re right, I have been overriding this frame-internal-border-width function from a macro defining functions for all the frame parameters. I’m changing the name used now.  You may close the bug report; sorry.
