Gnome-power-statistics will not refresh unless a button is clicked in the window

[Rafael P.]

Graphs and data will not refresh automatically in the window. To display new collected power data, an action must be taken
e.g. in the Laptop Battery>History tab, one must click the "Show data points" checkbox in order to display all the data points taken since the previous refresh (data points taken every 30 seconds)

This is a regression. It first appeared with Oneiric, if I remember well.

To reproduce:
- Open gnome-power-statistics through gnome panel bar>battery icon>battery
- Go to laptop battery from the left list
- Go to History tab: the graph will not refresh when new data points are taken
- Click on "Show data points" or "Use smoothed line": the graph (and info in the "Details" tab) is updated with the last data points
