I doubt that GoogleBot will disregard your robots.txt as a result of also having it indexed. A quick search for the phrase turns up 3 of the largest web sites (popularity-wise) with an indexed robots.txt file - WW, Whitehouse and Google's own. Brett or an administrator could confirm if robots.txt is being disregarded for this site. I will speculate and say 'it ain't so'.

Is your robots.txt listed in your sitemap file? It seems to me that *might* be considered a link.
