nipxkgs manifests list "git" origins as "urls"
It's currently worked around in the lister  but the surest fix would be that the manifest corrects it itself.
There is already a 2,5 year old task  about this in the upstream repository. I've pinged it (and also tried to have a look at it but i can't that fails... , i've opened another issue about it)
