logging errors with flask

I'm trying to log an error in a decorator function using app.logger.error(''), but it just doesn't work. In addition I cant debug this well and I can only see the response from the http client:

(I'm using nginx+uwsgi+flask)

HTTP/1.1 502 Bad Gateway

Server: nginx

Date: Sun, 12 Aug 2012 15:45:09 GMT

Content-Type: text/html

Content-Length: 14

Connection: keep-alive

Everything works great with out the line: app.logger.error('panic !!!')

def mydecorator():
    def decorator(f):
        def wrapped_function(*args, **kwargs):
            try:
                ip = Mytable.query.filter_by(ip=request.remote_addr).first()
            except:
                app.logger.error('panic !!!')
            else:
                dootherthing()

            resp = make_response(f(*args, **kwargs))
            h = resp.headers
            h['add-this-header'] = ":)"
            return resp
        return update_wrapper(wrapped_function, f)
    return decorator

It seems that it is out of context or something.
