I can confirm the issue on Karmic. Note that I've had a look at the package in Lucid, and it's not fixed there. It seems to me that all that's needed is to add an entry for "application/vnd.openxmlformats-officedocument.presentationml.slideshow" in /usr/share/mime/packages/freedesktop.org.xml. I don't know where to look for the upstream reference version of this document, though.
