It is mostly harmless: your tag level is undef and you don't have
the $log_recip_templ disabled. Instead of an '-' in the per-recip
log you'd get an empty string as a logged value of tag level.

Please delete or comment-out the line:

   for ($tag_level,$tag2_level,$kill_level) { $_ = 'x'  if !defined($_) }

at or near near line 13120 in amavisd.
