amarok-trinity depends on libnjb5 (why?) As does gnomad2, although it was removed from squeeze (lenny version works fine here on squeeze) Maybe they will remove libnjb5. For anyone getting aggravated by many lines of sysfs error messages on boot it is because: http://bugs.debian.org/cgi-bin/pkgreport.cgi?pkg=libnjb5;dist=unstable#_0_3… A quick fix (as root): sed -i 's|SYSFS|ATTR|'g /etc/udev/libnjb.rules
