Comment 5 for bug 569195

I can confirm this bug. There is another workaroud that works perfect for me:

Instead of using

${battery_bar 8,150}

I set the variable

default_bar_size 150 8

(yes it is the other way: "height,width" for battery_bar and "height width" for default_bar_size [also a blank instead of a comma]) and can just use $battery_bar
