I've re-run our migration script on all of our modules over the weekend.
There is a stdout/stderr file for each module here:

http://svn.gnome.org/migration

There is also a viewcvs set up, so we can see how well (or if) the
modules were migrated. In some cases, it fails to convert them. I have
prepared a list of those that didn't work here:

atomix
balsa
beast
bonobo-activation
dasher
desktop
dia
display
doc
eel
el
encompass
eog
epiphany
evolution
factory
fnlib
freeducweb
f-spot
galeon
gal
gb
gimp
gimp-help
glade
glib
gnomacs
gnome-applets
gnome-common
gnome-control-center
gnome-core
gnome-desktop
gnome-mag
gnome--
gnome
gnome-panel
gnome-session
gnumeric
gtk--
gtkhtml
libbonobo
libgnome
libgnomeprint
libgnomeui
libgtop
libgtop-backends
libical
livecd-project
locale
main
nagios
nautilus
po
reef-py-modules
sawfish
sensor
sun-patches
usability-proposals
utils

>From what I can make out, many of the errors are related to the modules
having tags and branches with conflicting ids, or where a file exists in
both in and out of Attic. I'm not sure how best to resolve these
conflicts.

you tell me what modules you'd like to investigate further, I'll roll up
the CVS archive and make them available to you. I just checked the size
of those modules listed above and chose a couple of examples to get you
started:

http://www.gnome.org/~rossg/eog-cvs.tar.bz2 (3Mb)
http://www.gnome.org/~rossg/libgnome-cvs.tar.bz2 (2Mb)

And, if the largest (probably most complex) module, in case you want to
test that too:

http://www.gnome.org/~rossg/evolution-cvs.tar.bz2 (~125Mb)

Any advice greatly appreciated :) Thanks.

Yep, probably best we let the module maintainers work out what best to
do there.
