	There are some options:
	* In the case of what you're trying: I think you need to reset the
stream position before beginning to output. If not, you'll get it in the
very last position written, and then, empty data.
	* You could read directly from the buffer of the stream you created
(i.e. creating the camel mem stream with a GByteArray).
	* Or you could create a new stream of the buffer of the camel mem
stream, and read from it.
