#122 Fatal error calling isAllowed() on a non-object on timeline page

[Ben Roberts]

Viewing the backups timeline page, and clicking on the previous day arrow a few times leads to an error and the active user is logged out requiring reauthentication to access any further content.

Webserver error logs show:

PHP Fatal error:  Call to a member function isAllowed() on a non-object in /usr/share/webacula/application/layouts/default/main-menu.phtml on line 25, referer: http://backups.example.com/job/timeline

Affects webacula 5.5.1-1.el6 on RHEL6.4 with php-ZendFramework.noarch 1.12.3-1.el6.
