You have identified a bug which was fixed in colordiff 1.0.9 - see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=470835
In fact, in your report, you note that the problem does not exist in the most recent version of colordiff. This recent version is included in Karmic. Given that this is the case, I don't believe anything else is required here.
