Bug: Battery widget only showing one battery out of two after resume from standby

[Joschi Brauchle]

Hello,

I am running KDE 4.11.x on an Lenovo Thinkpad T440s with two batteries.

The KDE battery widget works fine after the initial boot and shows the 
correct values for both batteries.

But after a standby and resume cycle, in about 25% of the time, the 
battery widget is missing to display one battery (currently BAT0 is 
missing).

This is the output of "upower -d" after resume:

Both batteries are displayed there, but the battery widget only shows 
one (BAT1) battery installed and charging.
