Comment 5 for bug 989991

Analysis on this bug:
There was a patch to disable the use of a CD when wubi.exe was run standalone: http://bazaar.launchpad.net/~ubuntu-installer/wubi/trunk/revision/265

Now instead of 'find_any_cd' passing back the path and distro it passes back 'None' and 'None'. However, there is another method that is called that looks for the CD 'find_cd' (why this action needs to be performed twice I haven't determined). And this method does not pass back or set the distro object. So, the net effect is that Wubi will still use the CD if it finds it... but if there is something wrong with it, it will then fail with this Nonetype object has no attribute 'getinfo'.

I started writing a patch, but haven't had time to test it or confirm my analysis. I just wanted to note what I've found here, so that it's documented.
