  ALT+PrtSc not recognised: breaks built-in screenshot function

Bug description:
  Binary package hint: xkeyboard-config

  On an EN-GB keyboard (and maybe others) ALT+PrtSc is the default
  keyboard shortcut for "Take a screenshot of a window" as configured in
  System -> Preferences -> Keyboard Shortcuts. However the system
  doesn't seem to respond to that keyboard combination at all. Pressing
  ALT+PrtSc on a default Maverick install does nothing. Indeed
  attempting to _set_ that keyboard shortcut in the Keyboard Shortcuts
  dialog results in it not being registered.

  Workaround:
  sudo sysctl -w kernel.sysrq=0

  Steps to reproduce:-

  1) Try to screenshot the entire desktop with PrtSc - this works
  2) Try to take a screenshot of one active window with ALT+PrtSc - nothing happens.

  Additionally

  1) Navigate to System -> Preferences -> Keyboard Shortcuts
  2) Scroll down to Desktop -> Take a screenshot of a window, and then click that line in order to set a keyboard shortcut for the action
  3) Press ALT+PrtSc - nothing happens
  4) Press a different keyboard combination such as CTRL+PrtSc or Super/Windows+PrtSc - this works

  Additionally

  1) Open a terminal
  2) Run 'xev' and then press ALT+PrtSc. Observe data in the xev terminal window when ALT is pressed, but nothing for ALT+PrtSc

  Seems a fairly critical regression bug given we document this keyboard
  shortcut in the help, and it's very commonly used by documenters and
  people getting support. It works fine in previous releases.
