    location: Initialize permissions
    
    The permissions hash is initialized after consulting the permission
    store, however the lookup is skipped for requests that cannot be
    resolved to an application, resulting in an error when accessing
    the uninitialized hash for saving. Just make sure that the property
    is always initialized to avoid that error.
