And that's exactly how we quick-fixed it :)

    def getUser(self, name):
        """Return the named user object or None if no such user exists"""
        try:      # koos elluäratamisega
            try:
                ob=self.sqlUserQuery(username=name)
            except:
                conn = getattr(self,self.conn_id)
                conn.connect(conn.connection_string)
                ob=self.sqlUserQuery(username=name)
        except:
            return None
        if not ob:
            return None
        ob=ob[0]
        return User(sqlattr(ob, 'username'),
                    sqlattr(ob, 'password'),
                    sqlattr(ob, 'roles'),
                    sqlattr(ob, 'domains'))

It does not find or solve the original problem, but at least it revives it
automatically
