** Description changed:

- Ubuntu version: Ubuntu Artful Aardvark (development branch), Release: 17.10
- gnome-software package version: 3.26.0-0ubuntu2
+ [Impact]
+ GNOME Software crashes if a broken snap is installed.
  
- Expected: To be able to use the application.
+ [Test Case]
  
- What happened instead: The application crashes after several seconds.
- Bug replicated every time the application is opened, rending it entirely
- unusable.
+ 1. Create and install a local snap:
+ $ mkdir -p /tmp/broken-snap/meta
+ $ printf "name: broken-snap\nversion: 1\n" > /tmp/broken-snap/meta/snap.yaml
+ $ sudo snap try /tmp/broken-snap
  
- Journald shows a segfault, as per attached snippet.
+ 2. Break the snap
+ $ rm /tmp/broken-snap/meta/snap.yaml
  
- ProblemType: Bug
- DistroRelease: Ubuntu 17.10
- Package: gnome-software 3.26.0-0ubuntu2
- ProcVersionSignature: Ubuntu 4.13.0-12.13-generic 4.13.3
- Uname: Linux 4.13.0-12-generic x86_64
- ApportVersion: 2.20.7-0ubuntu1
- Architecture: amd64
- CurrentDesktop: ubuntu:GNOME
- Date: Fri Sep 29 21:01:06 2017
- EcryptfsInUse: Yes
- InstallationDate: Installed on 2017-09-14 (15 days ago)
- InstallationMedia: Ubuntu 17.10 "Artful Aardvark" - Alpha amd64 (20170912)
- InstalledPlugins:
-  gnome-software-plugin-flatpak N/A
-  gnome-software-plugin-limba   N/A
-  gnome-software-plugin-snap3.26.0-0ubuntu2
- SourcePackage: gnome-software
- UpgradeStatus: No upgrade log present (probably fresh install)
+ 3. Confirm the snap is broken:
+ $ snap list
+ Name VersionRev   Developer  Notes
+ broken-snap x1   try,broken
+ 
+ 4. Restart gnome-software
+ $ killall gnome-software
+ 
+ 5. Open GNOME Software and go to installed tab. Wait for items to load.
+

related code.
