Comment 5 for bug 549799

I can confirm this bug in Beta1 with all updates applied.
Ubuntu 10.04 beta1 AMD64
When, for example, "apt-get update" is running the icon appears in the pannel (grayed out). But when the command finish the icon dissapears, even if there is updates to apply; and never appears automatically.

I have the gconf entry /apps/update-notifier/auto_launch as false
