Indeed, accountsservice sends a reply even when the client talking to it doesn't want one. The dbus daemon doesn't remember messages that have NO_REPLY_EXPECTED set, so the replies from accountsservice look like unsolicited messages to it and it denies them.
Gnome bug #755421 argues that this should be fixed in gdbus, and I agree. gdbus automatically sets NO_REPLY_EXPECTED when no callback is given, so it makes sense that it also handles the server side by discarding replies for such messages. I've attached a patch upstream. ** Bug watch added: GNOME Bug Tracker #755421 https://bugzilla.gnome.org/show_bug.cgi?id=755421 ** Also affects: glib via https://bugzilla.gnome.org/show_bug.cgi?id=755421 Importance: Unknown Status: Unknown ** Changed in: accountsservice (Ubuntu) Status: Confirmed => Invalid ** Also affects: glib2.0 (Ubuntu) Importance: Undecided Status: New ** Changed in: glib2.0 (Ubuntu) Status: New => Triaged ** Changed in: glib2.0 (Ubuntu) Importance: Undecided => High -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1488344 Title: dbus rejected send messages To manage notifications about this bug go to: https://bugs.launchpad.net/glib/+bug/1488344/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
