Emacs connects to system bus, but not to the session one

Question

The system bus works fine

(dbus-init-bus :system)

returns nil, as it should.

However, connection to the session bus

(dbus-init-bus :session)

raises

(dbus-error "No connection to bus" :session)

qdbus in the command line works just fine with both buses. It even works from within eshell, if that is of any concern.

Neither emacs nor emacs --daemon connect.

Do you solve this problem? I have the same problem but only on `emacs --daemon` on version `24.3.1` on Linux. BTW, some users pointed that: https://www.reddit.com/r/emacs/comments/2d4c1m/emacs_daemon_dbus_error_no_connection_to_bus/ — Manoel Vilela, Nov 26 '17 at 23:52
Sorry, I mistype my emacs version here. I meant: `25.3.1`. Trying version 27... — Manoel Vilela, Nov 27 '17 at 02:58

Which version of Emacs are you using? One version (before 2012-05-25) only looks for the DBUS_SESSION_BUS_ADDRESS environment variable, while a more recent one uses a library function that also looks in ~/.dbus/session-bus I think.

Did you try this before running emacs: eval $(dbus-launch) export DBUS_SESSION_BUS_ADDRESS
