[Mimedefang] Should I be concerned

[Mike Smith]

 Hi all,

 I'm getting a ton of these errors in a row in /var/log/maillog

mimedefang-multiplexor: Slave 15 stderr: Use of uninitialized value in length at
/usr/lib/perl5/site_perl/5.6.1/i386-linux/MIME/QuotedPrint.pm line 96, <GEN112> line
1.

down to
mimedefang-multiplexor: Slave 15 stderr: Use of uninitialized value in length at
/usr/lib/perl5/site_perl/5.6.1/i386-linux/MIME/QuotedPrint.pm line 96, <GEN112> line
89.

 Line 96 is this :
$eol = "\n" unless defined($eol) || length($eol);

 Should I be concerned with these?

 This doesn't happen on all mails, just every so often. But there are a ton of em.

 Any help would be great. Currently running MD 2.30 - SA 2.44 and have MIME-BASE64-2.16

 Thanks,

 - Mike
