Some advice on the spamassassin mailing lists suggests that there's a bug in NetAddr::IP 4.049 (Debian package libnetaddr-ip-perl).
The recommended fix is to use 4.048 or 4.055+. (Bug #601601 has similar symptoms, but I think it's different.) -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
