web2py 2.11 error on new install SESSION ISSUE

[use_web2py]

Can some one look into this! I get this error after installing a new app from an existing w2p file.

Traceback (most recent call last):
  File "/home/www-data/web2py/gluon/main.py", line 436, in wsgibase
    session.connect(request, response)
  File "/home/www-data/web2py/gluon/globals.py", line 961, in connect
    session_pickled = pickle.dumps(self, pickle.HIGHEST_PROTOCOL)
  File "/home/www-data/web2py/gluon/storage.py", line 56, in <lambda>
    __getnewargs__ = lambda self: getattr(dict,self).__getnewargs__(self)
TypeError: getattr(): attribute name must be string

After installing the file, from the admin screen click on the "clean" option (this should clear your cache, session, errors content). See if this helps.
If that doesn't work, please take a look at the discussions related to this in the group. Search for "pickle.HIGHEST_PROTOCOL".
