Perhaps I've gotten used to the idea too much that Spamassassin hardly gives false positives. The only time that's happened to me, was with mails that have all the charachteristics of spam, but are not really spam. Mails like newsletters from telephonecompanies and such (which they send out with bulkmail software intended for spamming it would seem, judging by Spamassassins matches)
