Version-Release number of selected component (if applicable):
Can be reproduced on a virtual machine (see example below), but same will happen with other devices
Steps to Reproduce:
1. xinput set-prop "ImEXPS/2 Generic Explorer Mouse" "Device Enabled" 0
2. start gimp, Edit, Preferences, Input Devices, Configure Extended Input Devices
