IOError: Illegal Seek in django admin

[Andre P LeBlanc]

I'm using django 1.2.5, I've modified my wsgi handler to use
twod.wsgi's DjangoApplication, my site seems to work normally, until I
try to access the admin, when I get the following traceback:

Hello, Andre.

It seems like Django Admin is reading the POST arguments in a GET
request, which it didn't do in Django 1.1.X.

I've committed a fix for that invalid operation in the "1.1" branch:
https://github.com/2degrees/twod.wsgi/commit/1bb3c92819ee38400d5a1613518551c4020173e3

I'm not comfortable releasing this to PYPI yet until it's undergone some
real world testing, which we will be carrying out as soon as support for
Django 1.2-1.3 is complete in a few days/couple of weeks (see:
https://github.com/2degrees/twod.wsgi/issues/#issue/2 ).

Thanks for reporting this!

- Gustavo.
