	So - the patch looks like a reasonable workaround given the horror
implementations of the UNO stream / storage interfaces. Wow - we really
need some hero to do a complete re-work of the lifecycle, and path
access semantics of all those implementations [ with some decent unit
tests to boot ;-].

	Pushed to libreoffice-3-5 anyhow; two more ack's for -3-5-1.

	Thanks !
