sa-update failed for unknown reasons

Hallo, mein cron.daily bringt seit heute folgenden Fehler:

/etc/cron.daily/spamassassin: rules: failed to run FORGED_GMAIL_RCVD test, skipping: (Can't locate object method "check_for_forged_gmail_received_headers" via package "Mail::SpamAssassin::PerMsgStatus" at (eval 1288) line 1501. ) channel: lint check of update failed, channel failed sa-update failed for unknown reasons

Hat das noch jemand? Irgendeine Idee was da schief ist? Google liefert 0 Treffer zu der Fehlermeldung.
