The gdbus-close-pending test fails on glib at times due to a race condition. This is already known upstream; see the following bug for the test failure and another bug for the underlying problem: https://bugzilla.gnome.org/show_bug.cgi?id=723788 https://bugzilla.gnome.org/show_bug.cgi?id=723719 The latter has a proposed patch for this, but it is not accepted yet.
skipped in 2.40.2 until upstream cares about it
