Does the document open correctly with such stub?
AFAICT it does.
I can view/edit all slides, though some have sometimes wrong layout/symbols in them (like a vector arrow is not displayed) but that could be due to the fact that my ppt`s are made with MSOffice, and I don`t know how compatible FreeOffice is with that.
