Comment 2 for bug 1739713

Note: in addition to the patch, you will need to do one of the following to retain the connection between the AppStream data and the desktop file:
- Rename the desktop file to match the AppStream ID (i.e."org.inkscape.Inkscape.desktop")
- Add the following line to inkscape.appdata.xml.in: "<launchable type="desktop-id">inkscape.desktop</launchable>"

Relevant section of the AppStream spec: https://www.freedesktop.org/software/appstream/docs/sect-Metadata-Application.html

[note: not an AppStream expert, take this with a grain of salt, etc]
