labels are not translated automatically

[meltzow]

If I added a new Page, the label is not translated. Other translations are working fine.
For example

'wallpapers' => array(
'name' => 'wallpapers',
'options' => array(
'label' => 'menu_wallpapers',
'route' => 'zfcadmin/wallpaper',
'params' => array(
'action' => 'index'
)
)
),

I haven't done anything with translation yet. Feel free to submit a PR.
