Bad news, tried to start Plasma 5 with the patches to be greated by a
zillion of crashing processes, here a backtrace of one of them

Also konsole is now failing to start (this may be a misuse of api on
KUniqueApplication) but still not good to regress like that

Title:
  unity8 sometimes hangs on boot

Status in autopilot package in Ubuntu:
  Confirmed
Status in libusermetrics package in Ubuntu:
  Invalid
Status in qtbase-opensource-src package in Ubuntu:
  In Progress
Status in unity8 package in Ubuntu:
  Invalid

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.

  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

  Currently mako still fails a lot of tests when the silo is enabled.
  The nature of failures is random (different tests fail on each run).
