This issue has originally been reported by Marcelo Messias and others at Launchpad: https://launchpad.net/bugs/450951

The reported Tracebacks are looking like:

Traceback (most recent call last):
  File "/usr/lib/pymodules/python2.6/papyon/msnp2p/session_manager.py", line 53, in <lambda>
    lambda tr, blob: self._on_blob_received(blob))
  File "/usr/lib/pymodules/python2.6/papyon/msnp2p/session_manager.py", line 164, in _on_blob_received
    session = self._sessions[session_id]
  File "/usr/lib/python2.6/weakref.py", line 54, in __getitem__
    o = self.data[key]()
KeyError: 1098564

The version of papyon used is 0.4.5

I had I quick look at the code, line 164 of session_manger.py makes no sense to me. If session is None, it is None because ._get_session() returned None, and this is because session_id was not found in the ._sessions dict.
What about replacing this line with "return None"?

Thanks,
Markus

Could somebody having the bug add an empathy debug log it would help us to debug the issue?
You can get it in the empathy help, debug dialog by selecting butterfly in the combo, check for informations you don't want to share before adding it there though and clean those or just copy the chunk before the crash
