Hi, Since this is an RC bug, and that it hasn't been addressed for the last 15 days, I've prepared an NMU. It simply removes that last one assert in the failing test, which is enough to have everything working again.
Debdiff is attached. I've uploaded to the DELAYED/5 queue. Cheers, Thomas Goirand (zigo)
