Can you run imapfilter with the -d, and when you see this error again send me
the output of the relevant /tmp/imapfilter.* debug file?

Also, you could try adding to imapfilter's interface.lua just before line 366:

	print(type(header), header, type(body), body)

... in order to find out what does it get from the server as header and body of
the message.
