wordpress 2.7 doesn't honour the "Comment author must have a previously approved comment" flag

[donpaolo]

In my wordpress 2.7 I have an user that sometimes writes a comment, and she always uses the same e-mail.

Every time she writes a comment I receive an email and I go and approve the comment, but the comment always remain in the moderation queue despite of the flag "Comment author must have a previously approved comment" in the /wp-admin/options-discussion.php page.

The previous flag ("An administrator must always approve the comment") isn't set.

Apparently the flag "Comment author must have a previously approved comment" isn't honoured.

Note: I don't have anything in the blacklist textarea nor in the moderation textarea.
I have set that the user must enter name and email in order to comment, and she always enter them. I haven't set that one must register in order to write a comment; and the default is that comments can be posted on articles.

Punting due to feature freeze. Reconsider with next release.

Can't reproduce in trunk. Reopen with detailed steps to reproduce (in wp 2.9-rare).

As I recall, version 2.7 had a bug that caused emoticons to count toward the link total before moderation rules were applied. Very likely something like that is happening on that site, and would not happen with current stable version.
