#965: SIMPLE Messages truncate the last 2 characters because they have the wrong
content length
--------------------+-------------------------------------------------------
Reporter:  mdknapp  |       Owner:  datallah               
    Type:  defect   |      Status:  new                    
Priority:  minor    |   Component:  winpidgin (gtk)        
 Version:  2.0      |    Keywords:  SIMPLE SIP CONTENT SIZE
 Pending:  0        |  
--------------------+-------------------------------------------------------
 It appears that the SIMPLE messages have the wrong computed content length
 causing a failure in interop with OpenSer. In the wire capture below (with
 identities changed but length maintained) the Content-Length should be 272
 characters but the Content-Length reports 270.

 With OpenSer this results in the last two characters of the message being
 truncated causing corrupting regular text messages and im-iscomposing+xml
 data. In the case of im-iscomposing+xml OpenSer returns a "415 Unsupported
 media type" because the "<presence>" tag is closed as "</presence"
 according to the OpenSer because it honors the Content-Length and then the
 xml parsers complain.
