wubi 12.04.1 contains incorrect metalinks for xubuntu, kubuntu, etc.

The metalinks for wubi.exe (12.04.1) still point at 12.04 releases of Kubuntu, Xubuntu, Mythbuntu etc. The Kubuntu one is incorrect in another way that was also true in 12.04 wubi.exe (different bug 1004173), the lubuntu one is correct but won't work because 12.04.1 != 12.04 (different bug 1043607), but the error for Xubuntu, Kubuntu, Mythbuntu etc. fail with message: Cannot download the metalink and therefore the ISO
