Data corruption bug

[drudd]

Exceptions thrown by the authentication layer are occasionally swallowed by the read function of SplitReader:

def read(self, num=None):
        val = ''
        try:
            while True:
                if num > 0:
                    new_data = self._get_current_file().read(num - len(val))
                else:
                    new_data = self._get_current_file().read()

                if not new_data:
                    self._current_file.close()
                else:
                    val += new_data

                if num > 0 and len(val) == num:
                    break
        except:
            pass

        return val

The naked exception handler is apparently there to ignore a StopIteration exception.
