I'm not sure why this was happening - some of the pages seemed to work
for me, while others were blank. I've tweaked some settings, so
hopefully it will work better now, but really I should just get
gmane.org set up to archive the group, since it provides a much better
interface, is much more responsive (to me, at least), and has a good
search facility (based on Xapian!).
