[OGL] Error updating a page

Got this error attempting to do a minor change to [[Minicabs]], having successfully done a major change.

My change: trying to add this page to category Transport

This is reproduceable - Done it 3 times. Could Earle please check the server logs and/or the database to see what the state of this page is.
