	Lovely ! :-) I finally got to review it.

	So - I think we don't have the resource to do much more than this.
Clearly we are going to want some to ask for some QA focus in 3.4.next
around document encryption [ particularly interacting with signed
documents from 3.5 ].

	Sorry for the delay; of course it is a big diff - in particular the
rampant header movement is particularly unhelpful for being able to
actually read what changed ;-) The removal of the XMemoryStream stuff is
interesting too, I assume that is made redundant by some other seekable
caching / fallback means. The property name defines clean up is nice but
not needed.

	Anyhow - assuming it has been tested thoroughly (and I assume so since
it's mostly 3.5 code being back-ported), and assuming we get some heavy
QA for the next 3.4.x release in this area - I think we should get it
in. The user experience regression of not being able to open newly
encrypted documents - and with such an hideous error message (that we
get without this fix) is just too bad :-)

	Out of interest - has Fedora shipped this yet ? and what was the
feedback like ?

	Thanks !
