Comment 6 for bug 1163107

Well, that was easy. I indeed can just search for wacom in dconf and change the "area" key value. This is of course a much nicer workaround than above, it still works after rebooting. I only used gconf, with which I couldn't find this key.
The key is in org > gnome > settings-daemon > peripherals > wacom > (very long string).

AFAIK this bug has not been fixed or attempted by anyone else.

Best of luck with fixing this Josh, and thanks for supplying us with a decent workaround. Please let me know if you need any testing done, I'd be happy to help!
