moon plug-in of cairo dock uses loads of network bandwidth

[PeterPall]

My computer has eaten up all the network bandwidth that is in my mobile phone contract for a month in one day. Which isn't this bad since in germany this makes the network slow, not expensive. But since disabling the display of moon phases in cairo-dock fixes the problem immediately I thought, I'd better report it anyway.
