Thanks. Trying that gives:

[eric ericscomputer ~]$ sudo xdg-mime query default
application/vnd.openxmlformats-officedocument.presentationml.presentation
[sudo] password for eric: 
libreoffice-impress.desktop libreoffice-impress.desktop

It looks to me like that part is right. I'm still wondering why, if it's
a MIME handling problem, Evolution isn't saying "I've got this .pptx
file but I don't know what to do with it" rather than "I've got this
attachment.dat file that I don't know what to do with but think is a
plain text file."
