Probably. dbus-launch polls its stdin under certain circumstances (which
is silly, but it's backwards-compatibility with code from long before I
got involved), and dbus-daemon might close it or end up with fds that it
opens unexpectedly becoming stdin.

Hopefully the fact that you have discovered this will make it easier for
me to make a smaller-than-lightdm reproducer.

dbus-daemon is designed to be launchable from X11 "autolaunching" in
arbitrarily precarious circumstances, so yes this is a bug, and I'm
opening a clone to track that. Thank you for making it non-RC so I can
carry on with my holiday :-)
