In this particular case, there was nothing to do on your side, that's why
Adrian reassigned
the bug, meaning "not really an issue for you".
The people who have routine in finding quickly whether this is true,
and who might already know what the problem is, are the people who
are having an overview of the whole archive because they are doing
archive-wide QA.
The average maintainer does not have any clue about archive-wide
breakages, or issues due to ongoing transitions.
Thank you Adrian and Santiago.
Now I can focus on the other issues with my package. :)
