#23 Unexpected flow data structures in the server

[Peter Eckersley]

While generating the flow table:

Weird error caused by flow ('\xc0\xa8\x01\x06', '\xa1\xaa', '@\x93\xbc\x18', '\x1eb', '\x06') (None, ('\xc0\xa8\x01\x06', '\xa1\xaa', '@\x93\xbc\x18', '\x1eb', '\x06'))
Traceback (most recent call last):
File "/home/pde/eff/switzerland/trunk/switzerland/server/Reconciliator.py", line 177, in prettyprint
TypeError: 'NoneType' object is unsubscriptable

The prettyprinter would have died, but we're invincible:
