[PyXMPP] StreamParseError in stream.loop_iter

[Shu Hung (Koala)]

Hello all,

I'm using PyXMPP to write a conference bot of Gtalk.
It generally works. Except when it runs for several hours, it stucks on a
strange error and quit.
This is the error:

===
Traceback (most recent call last):
  File "./foobar.py", line 160, in <module>

  File "/usr/local/lib/python2.5/site-packages/pyxmpp/streambase.py", line

    return self._loop_iter(timeout)

    return self.reader.feed(s)
  File "/usr/local/lib/python2.5/site-packages/pyxmpp/streambase.py", line
430, in error
    raise StreamParseError,descr
pyxmpp.streambase.StreamParseError: XML declaration allowed only at the
start of the document

What could be my problem?
Please suggest what I should do.

Thanks a lot.
