[arch-general] Battery Monitor Applet (kde4) hangs after s2ram

Hi, after I resume from s2ram my battery monitoring applet does not refresh anymore. It shows 100% loaded and plugged in all the time. I have to kill plasma every time in order to get the current charge. cat /sys/class/power_supply/BAT0/charge_now <- shows the correct charge. Maybe someone can help me. Notebook = Dell Inspiron 9400
