Indeed,
I have reported this bug at
https://bugs.launchpad.net/ubuntu/+source/udev/+bug/431055
Martin Pitt, has commited now a fix for this problem by splitting the
rule in two according to value existence of
ID_CDROM_MEDIA_SESSION_LAST_OFFSET

Do you know where to report the util-linux bugs?
There was a fork, util-linux-ng, but ubuntu seems to use util-linux
naming, but it seems to be based on -ng.
As usual, filling a lanchpad bug didn't really help.
I think that _ENC means that non printable chars are printed as \xNNN,
and indeed, here I see the long row of spaces after the volume name.
I am sure this is trivial to fix, but I want to know where to report
that (launchpad sadly doesn't count...)
