the linked Debian bug is against 2.0b5 not 2.0b7 as that's what is in
Debian. It does show the failure in `acquire_session_bus_name`. It looks
like the subsequent upstream releases fixed the other issues. So we can
trace this to gcc15 differences at least.

The code in question remains the same in the upstream source:
https://github.com/OpenPrinting/cpdb-backend-
cups/blob/master/src/print_backend_cups.c#L20
