Just exploring the above, I find that my 
~/.local/share/applications/defaults.list shows many lines that refer to 
files that don't exist in /usr/share/applications.  Is this a problem? eg:

audio/mpeg=totem.desktop

... but there is no totem.desktop in /usr/share/applications.

Also, in /usr/share/applications, there are a zillion files like:

libreoffice-writer.desktop.~1~

... what are these? They look killable to me.
