Remove duplicate GLib schema access rules from profiles that include abstractions/gnome.
Since commit 89c00513046f3a8ff7c3dafba8577cff35f298f4 in apparmor.git, abstractions/gnome gives read access to the GLib schemas. This change was first released in AppArmor 2.11.95 and first packaged in:
- Debian: 2.12-1 (Buster)
- Ubuntu: 2.12-3ubuntu1 (Bionic)
So it now seems safe to assume, at least in the ubuntu/19.04 directory, that the system's abstractions/gnome is recent enough to have these rules.
