Problem deploying Django-Mingus with Flup and Cherokee. Strange admin behaviour

I have a django-mingus blog running perfectly fine with the integrated development web server of django. It's installed in a virtualenv.

Once deployed using the django app wizard of cherokee 0.99.42 the admin pannel is displaying a strange behaviour. Sometimes all apps are displayed in the admin pannel sometime only a subset of the apps are displayed. It's always the same a开发者_如何学Gopps that disapear from the main admin view.

The manage.py runfcgi command is launched through the python interpreter installed in the virtualenv.

Do you have a method to track that kind of problem ? Could it be related to environment variable that are not set correctly ?

EDIT: Could this be a circular import problem ?

2nd EDIT: The same problem occur with nginx. Adding Debug=True to the ./manage.py runfcgi command make the setup stable.

I dropped all tables from the database, upgraded to last version of django-mingus after having deleted some dependencies to get them clean installed and I launched the scgi process using a shell script that activate the virtual environment before. Now everything seems to be stable.
