If i send a multi-part-message to the mailgw, i just got an error back:

---------------------------------------------------------------
Es gab ein Problem mit Ihrer Nachricht:
   Expected list, got <type 'str'>



Mail Gateway Help
=================
Incoming messages are examined for multiple parts:
 . In a multipart/mixed message or part, each subpart is extracted and
   examined. The text/plain subparts are assembled to form the textual
   body of the message, to be stored in the file associated with a "msg"
   class node. Any parts of other types are each stored in separate files
   and given "file" class nodes that are linked to the "msg" node.
 . In a multipart/alternative message or part, we look for a text/plain
   subpart and ignore the other parts.

[... and much more from the documentation...]

------------------------------------------------------------

Attached is the output from log during mailgw-run and the mail itself.
The error could be reproduced if you forward mail with "embedded" option
in thunderbird 3.x.

My roundup-version is:

root@attac-mailman:~# roundup-admin -v
1.4.15 (python 2.5.2)

Thanks for any hint!
