iMac System Preferences Keyboard Shortcut Settings have disappeared ... ?

Hi all,

Yesterday and again today, the Keyboard Shortcuts, System Preferences pain is empty on my Intel iMac running Lion/10.7. IE: the Settings options under Keyboard Preferences isn't populating any options, it's just empty.

This happens on and off throughout the day and no amount of waiting, restarting, opening/closing apps, re-syncing my aluminum Apple bluetooth keyboard, or checking for updates has helped.

Is anyone else having this issue and if so, is there a 'fix?' As I am typing this the settings started showing options once again, so the screenshot I was going to include is rather obsolete as far as helping give a better understanding of the issue, but I am including a shot of the Keyboard Settings pane when it is properly displaying items, just for app/preference clarification.

Thanks in advance!
