Affects: control-center (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
Description of the problem:
In gnome-keybinding-properties you cannot set the Pause or Print Screen keys as shortcuts (even though Take a screenshot starts out being set to Print!)

Steps to reproduce:
1. Start gnome-keybinding-properties .
2. Scroll down to Take a screenshot .
3. Click on Take a screenshot and press backspace. The shortcut will be set to Disabled.
4.  Click on Take a screenshot and press the Print Screen button.

Expected results:
Key to be assigned and Print to appear in the Shortcut column.

Actual results:
A warning dialog saying:
'The shortcut "Print" cannot be used because it will become unusable to type using this key.
Please try with a key such as Control, Alt or Shift at the same time.'
appears.

Additional information:
Pause suffers this problem too (I use it for Play/Pause) and if you set Shift-Pause as a keybinding then rhythmbox and totem will respond to plain unshifted Pause too.
