I'm not sure whether this is your problem, but please note, that logging
to a log file is not a good idea for django, which might spawn multiple

logging to log files works only from multiple threads (all spanweed by
the same process)

For very first tests you could use a stdout / stderr log handler or
lateron a socket logger.
