Bug Description

I just encountered that apps scope appear blank in Xenial's unity8-desktop session. After uptade && upgrade this morning I logged in unity8 but the apps scope appears empty. I also tried to run music player from music scope and it is not opening while music from scope works fine.

Enviroment: Unity8 running on Xenial+stable overlay

Distributor ID: Ubuntu
Description: Ubuntu 16.04.1 LTS
Release: 16.04
Codename: xenial

pic attached

1º Run unity8 on xenial+overlay
2º Check apps scope is blank

Expected result: Apps should appear in scope
Current result: Apps scope is blank

Add info: duflu from #ubuntu-unity confirmed that it is working in yakkety so it could be due to stable overlay

Victor, can you please check unity8-dash.log and scope-registry.log to see if anything obvious sticks out for you (and also whether the latest update that appeared in the overlay today resolves the issue for you)?

Re-opening this one as it seems Victor may be hitting a different issue after all.

It appears this is the cause here:

[2016-09-28 17:12:01.185] ERROR: clickscope: QueryBase::run(): Unable to find a keyfile for application 'sun-javaws' in container 'puritine2'

Seems to be a similar issue to the other bug, but at a different level.

OK, this is a bug in the Libertine back-end in UAL, as it's failing to try/catch inside a for loop that lists the installed apps, which gets bubbled up to the scoperunner.
