[Oops, accidentally sent a private reply the first time.] Hi, Sandro.
In general, it's possible to request temporary guest access to specific porterboxes, but I don't know how promptly such requests tend to go through. For the record, you can find relevant documentation at https://dsa.debian.org/doc/guest-account https://dsa.debian.org/doc/schroot At any rate, I've obtained a full backtrace from a powerpc system (partch). Sorry for not getting it to you earlier; I've had a busy weekend.
