Battery status seems to not be updating with "show battery percentage" off

Here's a bug I've noticed just now in Loki 0.4. Possibly a one-time thing, but might be worth looking at:

1. Disabled "Show battery percentage" in the popup menu for the battery indicator.
2. Battery indicator kept saying "Calculating" and the indicator icon was half-full, ergo I thought that I still had power.
3. Laptop shuts down.
4. I start it back up, seeing that the battery icon is still "Calculating"
5. I turned "show battery percentage" on and off again, and the correct percentage and battery status was shown, instantly going from "Calcuating" to "2%"...

Strange.

P.S A little suggestion now that I'm here -- Maybe add a "Disable touchpad when mouse connected" option to Switchboard mouse settings? KDE had it, and it was *really* useful... Especially now that I have to use a custom script to do it on Loki, as I keep touching my touchpad while typing... :disappointed:
