Pkg xen devel - Oct 2011 - Bug#643953: xen-utils-4.0: pygrub can not parse empty "root" statement in menu.lst

Package: xen-utils-4.0
Version: 4.0.1-2
Severity: normal

Trying to get a system that I've long had runing on the bare metal to
boot as a VM, I discovered that pygrub would not parse my menu.lst. The
problematic entry is this:

  # This is a divider, added to separate the menu items below from the Debian
  # ones.
  title           Other operating systems:
  root

pygrub's parser seems to expect that "root" will be followed by a
disk
specification. I get this traceback:

  File "./pygrub", line 669, in <module>
    chosencfg = run_grub(file, entry, fs, incfg["args"])

How is this a problem with pygrub? If the configuration file is wrong,
then it's normal not to boot, right? Or are you saying that it wrote a
wrong configuration file? If so, how this happened?
