If I remember there was a repository with many snapshots of different versions, already as package, which one can test quickly. That way we can restrict breakage range without git bisect. Do you have a link?I assume you mean "http://snapshot.debian.org"; .
Exactly. With this I did some more tests.

Break is received, since I see it as SC Alert, but I am not put into the console, maybe there is some further trick on these newer machine?
