Comment 8 for bug 381239

Exactly the same problem, you have already rebuilt the debhelper7 in your PPA:

https://edge.launchpad.net/~spring/+archive/ppa?field.name_filter=debhelper&field.status_filter=any&field.series_filter=any

It's not a bug anymore, it's design, you can only build source X once in your PPA and can only have one single instance of binary Y.

There is a clear issue with that, it does allow mistakes, once you've used a version, it's blacklisted forever. It requires a transitional upload with a version higher than the blacklisted one and lower than the next official package candidate.

Feel free to discuss this futher on lp-users ML.
