You just set your server to use the wrong MIME types.  The correct types 
for MSOOXML files are (apologies for any wrapping):

application/vnd.openxmlformats-officedocument.presentationml.presentation pptx
application/vnd.openxmlformats-officedocument.presentationml.slide      sldx
application/vnd.openxmlformats-officedocument.presentationml.slideshow  ppsx
application/vnd.openxmlformats-officedocument.presentationml.template   potx
application/vnd.openxmlformats-officedocument.spreadsheetml.sheet       xlsx
application/vnd.openxmlformats-officedocument.spreadsheetml.template    xltx
application/vnd.openxmlformats-officedocument.wordprocessingml.document docx
application/vnd.openxmlformats-officedocument.wordprocessingml.template dotx

I do agree, this should definitely be fixed upstream.

It was part of OO.o's 3.0 release, so one would certainly expect said 
support to be there.
