	Ok, prepared patch for camel (it applied without problems). The
changelog would be mostly the same:

* evolution-data-server/camel/camel-stream-filter.c:
  (do_write): if the camel_stream_write call does not write the
  full buffer but it's not due to an error, then loop to go on 
  writing the stream.
