test case for diagram problem
Attached diagram produced by opening file from Bug 43897 by msPP 2007 and saving it again to odp format under different name.
In 3.3.4 on Fedora 64 bit and in 3.4.3 on Windows XP it looks correctly
but in 3.5.1 on Fedora and Windows it looks wrong, both in editing and slideshow modes (all texts on slide is wrong)

screenshot on 3.3.4, all correct
Created attachment 59277 [details]
screenshot in 3.5.1 edit mode, all text is wrong
Created attachment 59278 [details]
screenshot in 3.5.1 in slideshow, no text at all
I am not sure if it is a bug in LO or in MS-Office (which generated your file in ODF 1.1). Indeed, if I save your file in LO 3.4.5 (packaged by Ubuntu) under a new name, then this file opens fine in LO 220.127.116.11 (default ODF format : 1.2 extended).

http://odf-validator.rhcloud.com/ tells this:
diagram problem.odp/styles.xml[2,713892]: Error: "id6" is used as an ID value more than once.
IMHO additional fault tolerance for LO will be useful
in 3.5.3 on Fedora 64 works correctly
