2.10 unexpected shutdown

GIMP version: 2.10

Operating System: Mac0s 10.13.6

Package: [flatpak? Installer from gimp.org? If another installer, tell us where from]

Description of the bug

Attempting to use Wacom Intuos Pro pen (latest update), specifically paintbrush, and Gimp closed.

Of note, Gimp won't recognize the Wacom pen by name, so I have to use a generic quartz.
