The only difference I can see is the extra bit set in the value of
'state'. Just to be sure, I reran my steps, and I can still reproduce
the problem on a clean reboot. My keyboard is a Dell USB model. I've
attached the relevant output of lsusb in case it matters.

Title:
Changing HUD key from 'Alt' to 'Alt' changes behaviour when numlock is
on
Status in “gnome-control-center” package in Ubuntu:
Confirmed
Status in “unity” package in Ubuntu:
Invalid
Bug description:
1. Initially, note that both HUD (using left alt) and window management menu
(using alt-space) work properly. The HUD shortcut in Keyboard Settings is
listed as "Alt L".
2. Make sure your keyboard's numlock is on.
3. Click on the setting to change it, and tap the left alt key.
4. The shortcut now reads as "Mod2 + Alt L" (note the addition of the
"Mod2"). The HUD is still assigned to left alt, but using alt-space now *also*
brings up the HUD, and not the window management menu like it should.
CCSM can be used to restore the correct shortcut.
