** Description changed: The following gdbus call is failing with a "Error: Timeout was reached" message: gdbus call --session --dest com.canonical.UnityGreeter --object-path / --method org.freedesktop.DBus.Properties.Get com.canonical.UnityGreeter IsActive This is being seen on krillin devices starting with image 106 from ubuntu-touch/devel-proposed. It doesn't happen every time, so far today, I've seen it 3 times from about 12 tests.
