Unsupported operand error when running Cron from cmd line with last PHP release

Got the error
Fatal error: Unsupported operand types in ...\drupal\sites\all\Modules\image_gallery_access\image_gallery_access.module on line 399

have a look in the code and found :

function _image_gallery_access_get_roles($user) {
// if the user has a uid, they get 1 as a role; otherwise 0.
$roles = array(intval((bool) $user->uid) + 1);
// add in their roles
$roles += array_keys($user->roles);

return implode(', ', $roles);
}

patched with

function _image_gallery_access_get_roles($user) {
// if the user has a uid, they get 1 as a role; otherwise 0.
$roles = array(intval((bool) $user->uid) + 1);
// add in their roles
$roles = array_merge($roles,array_keys($user->roles));

return implode(', ', $roles);
}

seem to work well now
