I doubt that this topic belongs to stackexchange. People already 
complained about asking questions about the push url in autoproj on 
robotics.stackexchange.com.

This is maybe a bug and worth a discussion about the behaviour of 
autoproj snapshot. The target audience of this are developers, not 
users. Therefore I think that rock-dev is the right place.

Christian
