Bug Description
When touching an unmapped tablet button, Xorg crashes. This happens immediately when working in Gimp and might need a few presses when Gimp is not open.
This bug is very consistent and I can repeat it always, even after a reboot.
Workaround: I configured all unmapped buttons on the tablet to map to <alt>+<tab> and this seems to prevent the crashes. Of course, this does not fix this nasty bug.
I have a Wacom Intuos Pro 2 M attached to a Dell XPS 13 9380 laptop with Ubuntu 18.04.3 LTS.
/var/log/kern.log shows the lines like the following:
kernel: [ 1710.477890] rfkill: input handler disabled
kernel: [ 1710.477890] rfkill: input handler enabled

Updates:
1) The workaround is only temporarily working. After some time of handling both the mouse and the Wacom tabled, Xorg consistently keeps crashing. Obviously, this is making using the tablet under Ubuntu unworkable.
2) I tried using the tablet in a Wayland session and that seems to solve the crashing of the whole session. However, after some time the buttons and scroll wheel on my mouse stops working and I need to restart the session to get it to work again. Unplugging and reconnecting any or both USB devices does not fix the buttons on the mouse.
A wild guess: maybe the same bug in the kernel is causing Xorg to crash and to break mouse buttons when running Wayland.
