Matches null string many times in regex?

[Evan Platt]

Seeing the below error quite frequently...
Oct 29 08:47:06 espphotography spamd[12945]: (?:(?<=[\s,]))* matches 
null string many times in regex; marked by <-- HERE in 
m/\G(?:(?<=[\s,]))* <-- HERE \Z/ at 
/opt/local/lib/perl5/5.8.7/Text/Wrap.pm line 46.\n


Line 46 of Wrap.pm is

while ($t !~ /\G(?:$break)*\Z/gc) {


Any hints or ideas?

Thanks.
