It would be nice if we could move to upstream's dbus 1.2.22 from the current 1.2.16. There are a significant number of bugfixes that were addressed in 1.2.18 and a critical threading issue was fixed in 1.2.22. The latter is evident when there is significant bus activity and fixes a locking issue in the watch handlers.
I need more concrete justification. What specific applications affected by which specific bugs? The release has only been out upstream for a whole day, so...
