[Bug 911810] Re: READ TOC fail in /lib/udev/cdrom_id for data DVDs burned using K3b

[Chow Loong Jin]

It seems that this only happens to multi-session disks. When I burnt
another disk (this time with no multi-session), the
ID_CDROM_MEDIA_TRACK_COUNT_DATA field returns.

  Some googling finds
  <http://mailman.archlinux.org/pipermail/arch-releng/2010-June/001101.html> which
  mentions that reverting
  <http://git.kernel.org/?p=linux/hotplug/udev.git;a=commitdiff;h=58e178894bfc040834e1270c6fe9b9fdef513550#patch1>
  works around the issue.
