Bug Description

Please note that it's not entirely clear if this is an upstart-app-launch bug. It's our first lead. This bug causes random failures (very rarely) in security autopilot tests.

As seen in the smoketesting results:
http://ci.ubuntu.com/smokeng/trusty/touch/mako/156:20140131:20140115.1/6364/security/719045/

I was able to reproduce the same test failure but on random click apps when running the test on my local mako machine.
Some logs:
http://paste.ubuntu.com/6850227/ - the DEBUG output from upstart for the failing application

The same problem seems to cause many application autopilot tests failing as well - it seems that upstart-app-launch cannot lunch applications sometimes. Reverting upstart-app-launch and running autopilot test suites results in everything passing, while there are random failures with the latest upstart-app-launch installed.

This bug seems to also affect normal applications in normal test suites, see latest smoketesting results:

This bug was fixed in the package upstart-app-launch - 0.3+14.04.20140129.1.is.0.3+14.04.20131218-0ubuntu1

---------------
upstart-app-launch (0.3+14.04.20140129.1.is.0.3+14.04.20131218-0ubuntu1) trusty; urgency=medium

  * Revert as usptart-app-launch showed to create a lot of randomness
    where applications are not starting even on mako. (LP: #1275017)

Okay, got a useful log message:

application-click-com.example.lp1245677_lp1245677_0.1.log:** (process:28517): WARNING **: Unable to exec 'echo Error' in '/opt/click.ubuntu.com/.click/users/phablet/com.example.lp1245677': Permission denied

Looks like APP_EXEC is not getting set before the job ends.
