+Subject: [PATCH 2/6] Fix crash when a standard bus isn't available
+
+Commit 1f6fa1f37a14742ddf53c753ce52d9dc048cd1dc added a way of
+suspending delivery of messages to standard buses when they connect and
+resuming delivery when the main loop starts. As a side-effect, we caused
+an attempt to do dispatching even after the connection failed. The D-Bus
+library doesn't like that.

+Task-number: QTBUG-51299
