Package: dbus-user-session Version: 1.10.0-1 Severity: serious Justification: maintainer says so
mbiebl and buxy pointed out that installing dbus-user-session does not force dbus-x11 to be upgraded in lockstep. This is bad, because older dbus-x11 versions ship a 75dbus_dbus-launch script that starts dbus-launch even if DBUS_SESSION_BUS_ADDRESS is already set. That would cause two buses to be launched, and a nasty split-brain situation. It is not possible to make `dbus-launch --exit-with-session` not launch if DBUS_SESSION_BUS_ADDRESS is set, because third party software relies on being able to (ab)use dbus-launch to get a new bus for regression tests and similar, because dbus-run-session(1) was only recently invented.
