Undefined variable: virtuemart_vendor_id

[r_ekkie]

I did a template change in my mail_html_header.php as told here:

http://forum.virtuemart.net/index.php?topic=109226.msg365917#msg365917

Now with the latste VM 2.0.20b it is giving me the following error
Undefined variable: virtuemart_vendor_id

I can't find any thing in the change logs that are over here:
http://forum.virtuemart.net/index.php?topic=113052.0
That this variable has been changed?
