Further investigation shows a deep hidden error with TextPreRotateAngle 
(bug 127437 and bug 127439). One of the results is, that the OOXML 
attributes vert="vert" and vert="vert270" seem to be correctly handled, 
if you roundtrip inside OOXML format, but they will always fail from 
OOXML to ODF and will fail, when combined with text box rotation from 
attribute "rot". More details are in the document AnalyseError.odt which 
is attached to bug 127437.

I think, that it is not possible to correct the error without 
implementing a proper changing of text box size and position of OOXML 
shapes in the import part.

Kind regards
