Hi Geoffrey,

Yes, this was only noticeable when I was logged in for a while, but it was
faster than 80 MB per day for me.  I don't think I had any indicator-*
packages installed.  At least I did not install any of them, maybe they
were already installed.  I would check again, but I threw debian on the
box.

I agree with your assessment, still leaky but manageable...
