[otrs] Error while trying to forward

Hi all, I got this error while trying to forward one non-delivery message: [Tue Jun 10 09:39:58 2003] [error] can't have encoding base64 for message type message/delivery-status! at /opt/otrs//Kernel/System/Ticket/SendArticle.pm line 131 Is this bug or? Message has three attachments - just regular nondelivery mail from mailer-daemon. With regards, Alex
