Hi guys,
In one of our views, we're getting the error below:
Traceback (most recent call last):
File "/usr/lib/python2.5/site-packages/django/core/servers/
basehttp.py", line 278, in run

backends/base.py", line 88, in encode
pickled = pickle.dumps(session_dict, pickle.HIGHEST_PROTOCOL)
UnpickleableError: Cannot pickle <type 'ImagingCore'> objects
By outputting debug strings, I've found out that this error occurs
after the view gets read and before the output to the browser.
'ImagingCore' here might be referencing to PIL (Python Imaging
Library) images which are stored in memory which are in turn are
stored in one of the objects which are stored into request.session in
this particular view.
I can confirm that the other parts of the view which does not process
the images are ok.
Versions used:
Django-1.0.2-final
we're using the development server that comes with django
So my question is: I'm wodering if there are any restrictions to the
data types which we can store in request.sessions?
