Question is, why indicator-application-service is running in your GNOME session?
Are you using some special systemd configuration? As this should not be running in GNOME but only in the Unity session. As for the other issues mentioned here, I think that it's not really an ubuntu bug, but it looks like a misconfiguration on the client part. Having two extensions trying to handle indicators isn't feasible (as they both want the same dbus name), so we can't do much. At least in future it won't be possible to install KSTatusNotificationIcon extension and the ubuntu indicators one together, so the issue will be less visible. ** Changed in: indicator-application (Ubuntu) Status: Confirmed => Incomplete ** Also affects: gnome-shell (Ubuntu) Importance: Undecided Status: New ** Changed in: gnome-shell (Ubuntu) Status: New => Won't Fix -- You received this bug notification because you are a member of DX Packages, which is subscribed to indicator-application in Ubuntu.
