 I seem to have a reproducible bug with the option "Comment author must
 have a previously approved comment".

 My client has a site that heavily uses guest commenting. They have
 selected the option "...must have previously approved comment".  This
 works well most of the time, however more frequently some guests
 (identified by email) are being flagged as not having a previously
 approved comment even though they do.  For one author (email) in question
 I am able to replicate this every time.
 - All other possible comment moderation disabled.
 - Comment as the guest in question, comment moderated.
 - Log in as admin, approve the comment.
 - Comment a second time as the guest, comment moderated again (shouldn't
 be)
 - Disable the option "must have previously approved..."
 - Comment a third time, now the comment is approved automatically.
 - Re-enable option "must have previously approved..."
 - Comment a forth time, the comment is moderated.

 This appears to be a bug to me, and I can reproduce it every time. Not
 sure how to troubleshoot this further from here.
