I think the exclamation points in your name are breaking the unicode parsing on the debian target. Looking at the documentation the maintainer field only supports ASCII characters.
I think it's likely that debian is more strict in it's interpretation of the formatting. And the quickest solution will be to remove the characters from the maintainer name. It could either be patched in the jessie specific branch in the release repo. The simplest solution is a rerelease without the characters.
B) Sourcedebs are triggered on a 15 minute cycle since people want them to come out quickly. We typically will roll back any releases which fail their sourcedeb jobs since it's rarely a platform specific issue. And if the sourcedeb is not working we might as well pull it from the farm.
