With latest silo 18 on mako #183 I still got the account deleted after
reboot.

And the spinner is still shown many times after clicking on "Sign In" in
the online accounts screen, both when started from system-
settings->account and from the apps scope "Install" button. Then it
takes more than 10 minutes for the user to regain back control, after
what looks like a unity8 crash.

While the spinner is shown, both online-accounts-ui and unity8 seem to
go on a merry dance while chewing at the cpu. (perhaps it's online-
accounts-lib the one inside the unity8 process, or it's qtdbus)

The top that alesage sees on arale looks similar to what I see on mako:

But, starting dbus-monitor doesn't show any unusual traffic that might
explain the high cpu usage.

Bug description:
  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. On the most recent
  failure, I grabbed a console and tried repeatedly to run the command
  from the shell, even after 2 hours the timeout was still being
  returned (after about 28 seconds).

  A copy of ~/.cache/upstart/unity8.log is here:
  http://paste.ubuntu.com/10179482/

  I have 3 test cases where the problem was observed:
  http://d-jenkins.ubuntu-ci:8080/job/vivid-boottest-qtchooser/1/console
  
http://d-jenkins.ubuntu-ci:8080/job/vivid-boottest-gsettings-ubuntu-touch-schemas/1/console
  http://d-jenkins.ubuntu-ci:8080/job/fjg-boottest/3/console

  In all cases, the test is using adt-run (from autopkgtest) to drive a
  test on the phone device. adt-run uses the above gdbus call to
  determine if the desktop is active. In all the examples, the device
  was freshly flashed.

  == Test Case ==

  bzr branch lp:unity8
  cd unity8
  while true; do adb shell rm -R "~phablet/.cache/QML"; ./tools/unlock-device 
|| break; done

  This reboots the device in a loop, and if this bug is not fixed by
  whatever proposed solution, it will hang at <30 boots.

  Timeline/Updates:
  2015-02-20: libusermetrics lands, causing (apparently) this boot problem to 
start happening rarely. 
http://people.canonical.com/~ogra/touch-image-stats/106.changes / 
http://launchpadlibrarian.net/198152771/libusermetrics_1.1.1%2B14.10.20141020-0ubuntu1_1.1.1%2B15.04.20150219-0ubuntu1.diff.gz
 ”I got a symbolic trace out of all the threads. It seems to be a dbus lock 
between usermetrics and networkmanager bits. We suspect a relation to QTBUG 
https://bugreports.qt.io/browse/QTBUG-44836.”
  2015-03-25: qtbase dbus update to support threads (instead of one main 
thread) in PPA 018 fixes the boot issue, but autopilot test suites start 
failing randomly.
  2015-03-27: an autopilot fix fixes a simple test case, and seems to fix UITK 
suite as a whole, but on krillin only
  2015-04-10: Further patches from upstream fix all AP tests.
  2015-04-23: Upstream continues to work on the patches but they have not yet 
been merged. AP:s pass, but U1 account gets removed usually after a reboot, 
even though apps can be installed after adding U1 account flawlessly for the 
duration of that boot.
