You should be able to fix this by going into /sw/fink/dists and typing 'cvs login' (hit enter when it asks for a password). If that doesn't work, you can delete the /sw/fink/CVS file and do a selfupdate-cvs again, it will re-download the fink tree.
Thanks, Benjamin. I also just saw the note in the FAQ suggesting
sudo find /sw/fink -type d -name 'CVS' -exec rm -rf {} \;
This seems to be working right now. If not I'll follow up your solution.
Kind Regards,
