gnome-power-statistics displays a disappearing "Details" tab

Binary package hint: gnome-power-manager

Immediately after running gnome-power-statistics, a tab titled "Details" is displayed with the following information (See attached screenshot):

    Device:
    Type: unknown
    Supply: No
    Refreshed: 1296615698 seconds

After clicking "Processor" in the left pane, the "Details" tab disappears and is replaced by a tab titled "Wakeups", which functions normally. There is no way to get back to the "Details" tab. The terminal output while this occurs is:
