* Fixed memory leak (thanks to Brian J. Tarricone)
* Custom bar colors now also work with special Gtk theme engine where
the previous code doesn't work (thanks to Brian J. Tarricone)
* Fixed bug that causes an invalid displayed string if no device name
was set.
* Fixed bug #972: The total value in the tooltip is now displayed with
fractional portion
* Fixed bug #962: Any errors about wrong configuration are now only
displayed in a dialog after changing configuration and not after
startup. This should help users whose network device is created after
dialing-in.
