KeyError: u'0800'

[ofergr]

From time to time I get the following exception:

Exception in thread StunReq:
Traceback (most recent call last):
File "/usr/lib/python2.7/threading.py", line 801, in __bootstrap_inner

bind_resp_msg = dictValToMsgType[msgtype] == "BindResponseMsg"
KeyError: u'0800'

What can be the cause of this? I can try and catch the exception, but I have no idea what to do with it :-)

Need to add that I have changed the list of STUN server to a more current one:
STUN_SERVERS = (
'stun.l.google.com:19302',
'stun1.l.google.com:19302',
'stun2.l.google.com:19302',
'stun3.l.google.com:19302',
'stun4.l.google.com:19302',
'stun.ekiga.net'
)

Also add handling of STUN server addresses which has port in it, as in the above list (simple split(':'), nothing fancy).

Thanks!
