I am always using "Gnome", so I believe that I am normally on Wayland,
not X11. The bug has existed in F29 and F30, but noes not happen in
earlier releases.
Something is wrong then, because in that crash gnome-shell is running
as an X11 client. It's receiving an X11 protocol error from the X
server. These are fun because they're asynchronous, so the backtrace
doesn't actually include enough diagnostic information to do anything
about it. But if it really happens 50% of the time, then hopefully a
developer would be able to reproduce....
