Comment 2 for bug 1184629

Likely introduced by this change:

"Implement iwconfig bitrate setting"
http://bazaar.launchpad.net/~wicd-devel/wicd/experimental/revision/813

The line that causes the crash is trying to set a checkbox for the current bitrate, but there is not current bitrate for networks we're not currently connected to. It's a nice idea, but that change needs some work. I'd stick to 1.7.2.4 for now. Seems to be in a much better place.
