I've seen users in other threads with similar issues say that moving the database connection code into the try block fixes similar issues, but I'm not sure why that would be the case:

    db = self.env.get_db_cnx()
    cursor = db.cursor()
    cursor.execute('SELECT MAX(version) FROM wiki WHERE name=%s', (user_manual_wiki_title,))

I saw similar issues when doing updates to 0.12 over the weekend. I fixed the issues in 0.12 but will try and find time to have a play with this in 0.11 too and push a fix.

Resolution: duplicate
Status: newclosed

So this is actually a duplicate of #6902 (or rather the other way round as this one is newer!), but it's been fixed now so all should be well. Sorry for the delay.
