Re: [Evolution] How does evolution choose apps with which to open attachments?

[Emilio Recio <Emilio Recio jefferson edu>]

There's a big caveat to the information you posted. If you have nautilus
installed, and a few other file browsers, they use D-Bus. Gnome will
ignore anything in those desktop files and opt for a dbus session call
for starting particular apps over the freedesktop standard. It took me
two weeks to figure that out. I use KDE and couldn't figure out why
nothing was working after installing some gnome application.
