> Skip, thanks for the news. What would be the symptoms of that particular bug?

The tokenizer was generating certain tokens which it assumed would be
dotted quads (e.g., 73.73.103.110) but not checking that they actually
contained four elements. The result was an IndexError exception. This
error could only be triggered if you had either x-mine_nntp_headers or
x-lookup_ip set to True. My fingerprints are on the relevant bit of
code, so mea culpa.
