Comment 7 for bug 332356

This looks like a rhythmbox issue, some strace output below.

When I saw the cover art in the notification, this was in the strace output:

  open("/home/ken/.cache/rhythmbox/covers/Don Henley - Actual Miles: Henley's Greatest Hits.jpg", O_RDONLY|O_LARGEFILE) = 24

When I saw the rhythmbox icon in the notification, this was in the strace output:

  open("/usr/share/icons/hicolor/48x48/apps/rhythmbox.png", O_RDONLY|O_LARGEFILE) = 24

This at least shows that notify-osd is displaying the icon it is being passed.
