Build ID: M20080911-1700

Steps To Reproduce:
1. Develop a custom source provider
2. Open and close the Categories preference page
3. Do something to trigger a "source changed" event
4. Look for "widget disposed" errors in the log

More information:

It appears that the ActivityCategoryPreferencePage attaches its table label provider as an activity manager listener, but does not remove the label provider as a listener when the page is disposed.
