To find out which app grabbed your key you could use the debug keysym XF86LogGrabInfo; run

sleep 2; xdotool key "XF86LogGrabInfo"

and then immediately start pressing that particular key repeatedly, then check for output in /var/log/Xorg.log.

Or use xdotool to press keys + XF86LogGrabInfo at the same time, see falconer's post here
