Do any of these directories have a surprise file or directory with a name
starting
with "durus" in them?

I see you are using 2.6.5.  That seems good.

The string should start with '\x80\x02cdurus.persistent_dict\nPersistentDict\nq'
not
'\x80\x02cdurus.durus.persistent_dict\nPersistentDict\nq'.

I think this is the problem.  I'm not sure how it originates.
I noticed that qwitter imports Connection and FileStorage in an unusual way,
with "from " imports that are inside a function body.  I'm not sure if that has
an
impact on this, but it is unusual.
It looks like, when the FileStorage was initialized, the root was instantiated
after an import that somehow obtained a "durus.durus.persistent_dict" module.
That's not good.

Your site-packages directory should have a durus directory that has
a 'persistent_dict.py" file directly in it.  Is that what you have?  Do you have
a durus directory inside a durus directory anywhere?

Sorry to use jargon.  I mean it does not make run-time changes
to names in the durus module.  This seems like a pretty unlikely
possibility, but I thought I'd ask.
