        Hi,
I think the problem with xdg-mime is that it's a crossroad for
different desktop environments. When you run it under GNOME, then it
runs GNOME-specific tool. When you run it under KDE, then it runs KDE-
specific tool. And so on.

Evolution uses glib for this and relies on it. Instead of xdg-mime, try
`gio mime` (there's a space, not a dash). Eventually run xdg-mime like
it being run under GNOME:

   $ XDG_CURRENT_DESKTOP=GNOME xdg-mime query default application/pdf

which should use the gio, gvfs or gnomevfs (in this order, whichever is
found first) utility in the background.
        Bye,
