Good catch! Thanks for going until that point in debugging. This extract from the log explains that's going on: "Launch helper exited with unknown return code 0"
So the problem is on D-Bus side, it seems that the program responsible for starting the Platform backend exited without returning an error (0 means success). I don't know whether this can mean that the backend exited too early, or that the launch helper itself has a problem. I hope somebody familiar with D-Bus can help us on that point. ** Also affects: dbus (Ubuntu) Importance: Undecided Status: New -- users and groups prog blocked on first launch https://bugs.launchpad.net/bugs/411533 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
