Django raises IOerror in csrf.py middleware

Hello,

I received a traceback from Django and I'm unable to figure out where the error comes from.

The form is a basic picture upload form, I've read that this kind of errors do happen when the connection is broken before all data was sent, but here, the crash occured in csrf.py, which it was not in other error reports that I read.

So here's my traceback and my Middleware config, if someone has seen this, please tell me (and hopefully explain : D), because I'm kinda running out of ideas (and so far, I've been unable to recreate the error).

Thanks in advance !

Middleware:

MIDDLEWARE_CLASSES = (

    'middleware.loc.ForceDefaultLanguageMiddleware',

    'django.contrib.sessions.middleware.SessionMiddleware',

    'django_mobile.middleware.MobileDetectionMiddleware',

    'django_mobile.middleware.SetFlavourMiddleware',

    'django.middleware.locale.LocaleMiddleware',

    'django.middleware.common.CommonMiddleware',

    'django.middleware.csrf.CsrfViewMiddleware',

    'django.contrib.auth.middleware.AuthenticationMiddleware',

    'django.contrib.messages.middleware.MessageMiddleware',

    'middleware.technical.UserBasedExceptionMiddleware',

)
