Public bug reported:

I have a backlit keyboard on a stationary PC.
The back-light goes off at random intervals.
I'm a heavy user of numeric keypad. That turns into mouse-keys at intervals as 
well.

Both issues results in a rather annoying user experience. 
I have not been able to determine the reason or what lead up to this. But it 
often happen whenever I take a short break. (after a few minutes of inactivity)

Therefore I periodically run a script to turn the back-light back on and
disable mouse-keys.

It turns out that setting the back-light on, enables the mouse-keys
again!

Something is wired with this. But this last part is easy to reproduce
with this script:

#!/bin/sh
/usr/bin/gsettings set org.gnome.desktop.a11y.keyboard mousekeys-enable false # 
disables mouse-keys
/usr/bin/gsettings get org.gnome.desktop.a11y.keyboard mousekeys-enable  # 
reports false and mouse-keys are actually disabled

xset led on

/usr/bin/gsettings get org.gnome.desktop.a11y.keyboard mousekeys-enable # 
reports false, but mouse-keys are actually enabled!
/usr/bin/gsettings set org.gnome.desktop.a11y.keyboard mousekeys-enable false # 
disables mouse-keys again.
