upgrade from feisty to gutsy fails (amd64)

[Philippe Chartrand]

Binary package hint: libxml-libxml-perl

using Distribution Upgrade from 7.04 to 7.10

While installing the upgrades

first error in package
libxml-libxml-perl
subprocess post-installation script returned error exit status 255

causes shorewall documentation generation (scrollkeeper) to fail
Setting up shorewall-doc (3.4.4) ...
/var/lib/scrollkeeper/pt_BR/scrollkeeper_cl.xml:226: parser error : expected '>'
          <title>Edição web</t

...more...

and then

update-initramfs: Generating /boot/initrd.img-2.6.22-14-server
Errors were encountered while processing:
   libxml-libxml-perl
Traceback (most recent call last):

IOError: [Errno 0] Bad file descriptor
gutsy: Fatal IO error 9 (Bad file descriptor) on X server :0.0

The upgrade aborts now. Your system could be in an unusable state. A recovery will run now (dpkg --configure -a).
