...and they too refer to improper error handling by X11. I'm somewhat
baffled by the effect reported, though. Surely, an application
crashing the window manager is a bug in the latter, not the former?
What we've heard of before is that closing X11 windows with the window
manager crashes R, but this sounds like the other way around.

Except for the "95" bit I can empathize with it. (and the law of
inertia is strong for user interfaces in any case).
