0.16.3 upgrade issue...

Regarding the previously discussed issue with version 0.16.3 not working
when upgrading, at least I experience the issue of that 

$LU->_auth = NULL 
$LU->_perm = NULL

Which points to that the containers are not loaded (althought they load
without problems with the same config on 0.16.2). Can the problem be related
to that we are using MySQL as backend DB?
