After some conversations with jdstrand on #ubuntu-touch we may have concluded that it's unity8's responsibility to do the right thing (upstart-app-launch already does).

Two things are happening in this bug:
 * unity8 can't find the 'notes-app' executable
 * the app is using a shell script to launch the app

Unity8, when not using upstart-app-launch, should examine the Path in the .desktop file then do this:
 * cd $PathInDesktopFile
 * export PATH="$PathInDesktopFile:$PATH"

I think the former may already be happening. This mimcs the behavior of upstart-app-launch, which is correct. Please make sure that $PathInDesktopFile does not equal "." when implementing this.

The second thing is that an app should not be using a shell script to launch itself. The notes-app can be updated to use the '-I' option to qmlscene and simply not use the shell script. The works around this specific example, but this bug should be fixed in Unity8 as well for when apps don't use qmlscene, eg compiled code.

This shouldn't be handled in aa-exec-click because the chdir and the adjustment to PATH should happen prior to its invocation.

affects: click-apparmor (Ubuntu) → unity8 (Ubuntu)
summary: - aa-exec does not work when Exec not in PATH
+ cannot find click application when Exec not in PATH
