[Zope] len() of unsized object error

[Peter Bengtsson]

If found this TypeError description in many places in the mailing list archive, but no solution to my sendmail problem.

Code:
<dtml-sendmail mailhost="MailHost">
To: <<dtml-var email>>
From: <<dtml-var webmaster_email>>
Subject: Registration at <dtml-var sitetitle>

<dtml-var attached_email>

</dtml-sendmail>

If I do this...:
dtml-sendmail mailhost="MailHost"
To: <<dtml-var email>>
From: <<dtml-var webmaster_email>>
Subject: Registration at <dtml-var sitetitle>

<dtml-var attached_email>

/dtml-sendmail

... it doesn't return any errors and looks fine.
