update-manager 0.124.11, Ubuntu Karmic

1. Disconnect from AC power.
2. Start Update Manager.
3. Reconnect to AC power.

What happens:
2. An alert appears complaining that the computer is running on battery.
3. The alert stays up even though the computer is running on AC power.

What should happen:
3. The alert should disappear automatically.

<https:/ /wiki.ubuntu. com/SoftwareUpd ateHandling# alert>: "The secondary text for the alert should consist of one or more list items, depending on the exact situation ... Whenever the computer is running on battery, there should be an item (fixing bug 484249 and bug 494772) with exactly the same battery icon as the power status menu is currently using for the battery, and the text: “It’s safer to connect the computer to AC power before installing.” (fixing bug 426708). The item should automatically appear or disappear (with the alert resizing appropriately) if the computer starts or stops using battery while the alert is open (fixing bug 426710)."
