GET variable names replaced by 'e'

[martopolis@…]

I'm attempting to override the queryset() method to make a custom filter for the Change List Admin view. The idea was to append ?myview=1 to the URL and then check it like so:

if request.GETmyview == '1':
...

But everything I pass via the URL string is being replaced by the key name 'e' in the GET dictionary:

"Key 'myview' not found in <QueryDict: {u'e': [u'1']}>"

Curiously, this also happens in the final URL string. That is, the URL gets rewritten and redirected to ?e=1 as well.
