Class name must be a valid object or a string

[poxin13]

Using fresh install of Laravel 5.2 with make:auth done.

Everything appears to work great except when deleting a role. I get the error:

FatalThrowableError in Model.php line 945:
Class name must be a valid object or a string

in Model.php line 945
at Model->belongsToMany(null, 'role_user', 'role_id', 'user_id') in EntrustRoleTrait.php line 51

Creating a role is fine, as well as creating/deleting permissions.

More of an issue for the Entrust main repo, apologies.

I fixed this by editing EntrustRoleTrait.php

Line 46: ... Config::get('auth.model') ...

With

Line 46: ... Config::get('auth.providers.users.model') ...
