RX/TX rates shown from tray are 2.5x too high

In wicd-gtk there is a small connection info dialog which has receive and transmit rates. These are calculated by taking the number of bytes transferred over a five second interval (hard-coded as 5000) and dividing by 2,048 (self.time * 1024) to get a result in kB/s. self.time is 2. Hence the results are higher than the actual rates by 2.5 times. Not exactly high priority, I could happily live without that dialog completely. Or better yet stick the info on the tooltip ;)

The first values shown after opening the dialog are also massively high. I think the values "wrap" from the -1 which the byte counts are initialised to? Maybe don't show anything until real data is available?
