No application data on install, No screenshots after update

[Sean Davis]

When first installed, the "All" section displays something along the lines of "No application data available". At this time, going to the "Installed" section and viewing an application with current AppStream screenshots (tested with Catfish and Mugshot) shows those screenshots.

I then closed Gnome Software, and reopened the application. Now the "All" section shows featured applications, editor's picks, etc. I went back to the "Installed" section and viewed Catfish and Mugshot again. Now their screenshots are no longer displayed.

Looking in /var/lib/app-info/yaml/archive.ubuntu.com_ubuntu_dists_xenial_universe_dep11_Components-amd64.yml.gz shows no screenshots for catfish or mugshot in the appstream data.

Status changed to 'Confirmed' because the bug affects multiple users.

Now I am no longer seeing the screenshots on installation for Catfish and Mugshot. This leads me to another question (and maybe a new bug).

I see that there is a screenshot download error on http://appstream.ubuntu.com/xenial/universe/issues/catfish.html for http://screenshots.smdavis.us/catfish/catfish.png

The screenshot in question does exist, but on HTTPS (and is redirected with HSTS). I can (and will) fix this in the appdata, but I wonder if this should gracefully handle the redirect?
