Battery icon with problem with some themes

view full story

http://askubuntu.com – I'm using the elementary icon theme from their PPA, it's great, but have some problems. In almost all cases I fix it without any problem, but I can't solve this one. The battery icon is "missing" and it show and ugly battery icon, I don't have sure from where it came and how to change it. Does anyone have any information that can help me to fix it? I already tried to change the name of the file, copy from other themes, make inherent themes too, and nothing solve it. Ps.: Already "Googled" it, but just found some people with problems like "missing icon" or something like that. (HowTos)
