[web2py] Can't generate index.yaml

[devGS]

Hello,
I'm can't make my GAE Launcher to generate the indexes file. I tried
to clean the datastore locally, tried to play with  models/0.py file,
to place my own index.yaml in web2py folder with "# AUTOGENERATED",
but so far nothing have worked. I use Janrain for logging in, and the
only table at db.py is 'auth_user', please help.
Thanks.
