Menu entry 'Install all updates' does not work, if updates require authentication

[b3nmore]

Updating the system with help of the update notifier does not follow a consistent work flow. For a normal user it should work as follows:
- a notification appears,
- he clicks on the symbol and chooses 'install all updates',
- the updates process starts (possibly asking for authentication).

Now consider we have some 'normal' updates and some which require authentication:
- notification appears,
- he clicks on 'install all updates',
- the updates process starts (and installs all 'normal' updates),
- a notification appears again,
- he clicks on 'install all updates', nothing happens and
- the notification keeps notifying.

To really install all updates, he has to choose 'show updates' and in the appearing window 'Install now'. All very confusing.

I see this (mis)behavior in Xubuntus 12.04 and 12.10 desktop installation (update-notifier 0.119ubuntu8.5 and 0.126 ).

Status changed to 'Confirmed' because the bug affects multiple users.

Testing ISO for Xubuntu 13.04. Clicking on menu entry 'Install all updates' doesn't do anything. It doesn't seem to matter whether or not packages require authentication. The only way I can ever get it to update from this notifier is to click 'show updates' and then install from the dialogue that appears. I've noticed this in 12.10 as well.
