This bug has not been fixed. The reproducer in comment 1 still proves
that (in current vivid). That reproducer is a bit complicated, but I
wanted to have one which doesn't require an actual phone. But you can
easily reproduce that on an actual phone, too. Since I don't have
another click at hand, I just use the calculator and pretend it wasn't
installed already:

Uninstall the preinstalled calculator and remove the cache:

sudo rm -r /usr/share/click/preinstalled/com.ubuntu.calculator
rm ~/.cache/ubuntu-app-launch/desktop/com.ubuntu.calculator_calculator_*.desktop

It's now gone from "click list". Now install it again from an actual
.click:

wget http://people.canonical.com/~pitti/tmp/com.ubuntu.calculator_1.3.283_all.click
sudo click install --all-users --allow-unauthenticated com.ubuntu.calculator_1.3.283_all.click

There's an error about "Could not parse click manifest." for a
mismatching version, but that's fine. "click list" should now show that
com.ubuntu.calculator    1.3.283 is installed.

Note that ~ .cache/ubuntu-app-launch/desktop/ doesn't have a cached
entry for the calculator, as it was installed in a running session. And
it indeed can't be started due to that bug:

$ ubuntu-app-launch `ubuntu-app-triplet com.ubuntu.calculator`

** (process:5499): WARNING **: Unable to find keyfile for application
'com.ubuntu.calculator_calculator_1.3.283'

Clicking on the calculator icon in the dash doesn't work either.

Title:
  "Unable to find keyfile for application": clicks installed in current
  session don't create UAL cache, and UAL does not look for .desktop
  files in click pkgdir

Bug description:
  For testing/autopkgtest I want/need to run click apps and their tests
  in a schroot or container, as the turnaround with real phones and the
  emulator is way too large. But in a container, ubuntu-app-launch fails
  with

  $ ubuntu-app-launch `ubuntu-app-triplet com.ubuntu.calculator`

  ** (process:766): WARNING **: Unable to find keyfile for application 'com.ubuntu.calculator_calculator_1.3.283'
  init: application-legacy (com.ubuntu.calculator_calculator_1.3.283-1403523098604203) pre-start process (770) terminated with status 1

  In strace I see that it looks for the .desktop file in the following
  locations:

    /home/ubuntu/.cache/ubuntu-app-launch/desktop/com.ubuntu.calculator_calculator_1.3.283.desktop
    /home/ubuntu/.local/share/applications/com.ubuntu.calculator_calculator_1.3.283.desktop
    /usr/local/share/applications/com.ubuntu.calculator_calculator_1.3.283.desktop
    /usr/share/applications/com.ubuntu.calculator_calculator_1.3.283.desktop

  but not in the click dir:

  $ click pkgdir com.ubuntu.calculator
  /opt/click.ubuntu.com/.click/users/@all/com.ubuntu.calculator

  The workaround is to create the symlink manually, then it works:

  $  ln -s `click pkgdir com.ubuntu.calculator`/*.desktop .cache/ubuntu-app-launch/desktop/`ubuntu-app-triplet com.ubuntu.calculator`.desktop
  $ ubuntu-app-launch `ubuntu-app-triplet com.ubuntu.calculator`

  But that's certainly not something that autopkgtest should do.
