FWIW, you don't need to call iter_first() here:

if (g_mime_header_list_get_iter (ls, iter) && g_mime_header_iter_first 
(iter))

When you get the iterator, it starts at the first one.

Once you finish with the GMimeMessage headers, you'll want to iterate 
over the headers of the message's mime part (to get the Content-*) 
headers because the mime headers are stored on the mime parts themselves 
and not the message object.

If you want to get all headers of all mime parts within the message, 
you'll also need to traverse the mime hierarchy - but I suspect you only 
care about the top-level mime headers.

Hope that helps,

Jeff
