[Typo3-shop] no products in ###email_plaintext_template###

[Rick [Futuros]]

In my emails (plain text) i dont see any details about the products i 
ordered.

<!-- ###EMAIL_PLAINTEXT_TEMPLATE### begin
 Subpart used as template for the order-emails
 First line is used as subject for the mail.

  <!-- ###ITEM_LIST### end -->

<!-- ###EMAIL_PLAINTEXT_TEMPLATE### end -->

All the markers get substitued only the part between ###ITEM_LIST### stays 
empty. Or to be exact i get 4 empty lines.

I don't get why this is happening because the getBasket function is also 
used for others templates and then the output is okay.
I even substituted my markers for the standard template with the 
plain_text_email markers but the problem stays.

Anybody an idea what the problem is?
