Did you use the original dbus (without my changes) before yesterday?

What I changed is the internal service name for unique applications.

See bool KUniqueApplication::start(StartFlags flags).

E.g. org.kde.kmail changed to org.kde.kmail.unique-{pid}. But if you query for 
org.kde.kmail, dbus returns true, since internally it strips out the 
.unique{pid} suffix.
