[otrs] Software Error Forwarding ticket

Hello, I'm using OTRS 1.3.2 - got this recurring error when trying to forward a ticket to an external address: - Software error: Wide character in subroutine entry at path_to_otrs/bin/cgi-bin/../../Kernel/cpan-lib/MIME/Decoder/Base64.pm line 125. - The error only occurs for a particular ticket, I've had no problems fowarding other tickets. Any help would be much appreciated. OTRS has utf8 support enabled, BTW. regards Alex
