Comment 8 for bug 1970248

Missing 'where problems could occur' per https://wiki.ubuntu.com/StableReleaseUpdates#SRU_Bug_Template

And I do see significant risk of problems; while the mime handler for .deb files is incorrect, a diff of /etc/gnome/defaults.list vs /usr/share/applications/gnome-mimeapps.list shows a number of differences, including some types that are only handled in /usr/share/applications/gnome-mimeapps.list. Given that shipping /usr/share/applications/gnome-mimeapps.list was unintentional and it's so soon after release we might accept wholesale dropping of the file, however I would still want to see analysis of the impact.
