SpamAssassin daily update error

For several weeks, the CRON job which runs every day:

Code: [Select]

/usr/share/spamassassin/sa-update.cron 2>&1 | tee -a /var/log/sa-update.log
sends me back an e-mail with the following error:

Code: [Select]

Any clue what might be wrong?

I tried rebuilding the mail server (which conveniently upgraded ClamAV binary), also removing the folder with updated rules, but no idea what else may be causing this. I suspect that some updated rules are triggering the UTF issue?
