The log handler appends the stack trace to the log record here:

    def emit(self, record):
        """
        This gets called whenever a log message needs to get sent to the syslog. This method will
        inspect the record, and if it contains newlines, it will break the record into multiple
        records. For each of those records, it will also verify that they are no longer than
        MAX_MSG_LENGTH octets. If they are, it will break them up at that boundary as well.

        :param record: The record to be logged via syslog
        :type  record: logging.LogRecord
        """
        if record.exc_info:
            trace = self.formatter.formatException(record.exc_info)
            if not isinstance(record.msg, basestring):
                record.msg = unicode(record.msg)
            record.msg += u'\n'
            record.msg += trace.replace('%', '%%')  <------------------ HERE
            record.exc_info = None
        formatter_buffer = self._calculate_formatter_buffer(record)

The formatException method returns a str and appears to convert unicode to UTF-8. So, if an
exception contains either UTF-8 or unicode, this method returns a string containing non-ASCII.

This concatenation fails.

record.msg += trace.replace('%', '%%')

This results in the following exception:
