[Bug 1381102] [NEW] Apparmor stops applications from using GetArtistArt from the thumbnailer

 

Public bug reported:

While attempting to make the music-app run under confinement we noticed
that any Artist cover art is not shown from the thumbnailer.

This is the denial from the syslog:
Oct 14 01:29:14 ubuntu-phablet dbus[1654]: apparmor="DENIED" operation="dbus_method_call" bus="session" path="/com/canonical/Thumbnailer" interface="com.canonical.Thumbnailer" member="GetArtistArt" mask="send" name="com.canonical.Thumbnailer" pid=26358 profile="com.ubuntu.music_music_1.3.657" peer_pid=3667 peer_profile="unconfined"

Also it has been noted that in the file
/var/lib/apparmor/profiles/click_com.ubuntu.music_music_1.3.657,
GetAlbumArt exists but there is nothing for GetArtistArt.

  # Allow communications with thumbnailer for retrieving album art
  dbus (send)
       bus=session
       interface="org.freedesktop.DBus.Introspectable"
       path="/com/canonical/Thumbnailer"
       member="Introspect",
  dbus (send)
       bus=session
       path="/com/canonical/Thumbnailer"
       member=GetAlbumArt,
