I don't see any tickets with launchpad_bug set on PIDA, so I don't think this has ever worked there. Although I setLaunchpadBugId in the traceback, can you confirm that other calls like bug_info do succeed (or have in the past)? I'm setting up my test instance to work on MySQL and will get back to you tonight (PDT).
My intuition is that it's a db-backend issue, and some searching confirms that MySQLdb has caused that specific exception before - http:// mail.python. org/pipermail/ python- list/2008- June/666728. html.
