Weird, I use this code:

headers = {'Content-Type': 'text/xml; charset=utf-8'}
c = 
suds.client.Client('file:///home/jkugler/crc/local-tools/services.wsdl',
                       transport=ntlm,
                       headers=headers)

And Suds still tells me it's only sending 'text/xml' as the type.  
Leading to the same error.

DEBUG:suds.client:sending to (https://myserver/ews/exchange.asmx)
message:

</SOAP-ENV:Envelope>
DEBUG:suds.client:headers = {'SOAPAction': 
u'"http://schemas.microsoft.com/exchange/services/2006/messages/GetFolder"', 'Content-Type': 'text/xml'}

In the failed message back from the server, it starts:

<?xml version="1.0" encoding="utf-8"?>

Is that what needs to be added?
