desktop file but such a situation would also happen with evince, amIn comment 3 you write the fundamental bug lies in shotwell viewer
I right?
Actually I just tried and changed the default PDF viewer and I have
no way to get it reset. (clicking on Reset remove the selected choice
but doesn't set evince back); the only fix was to edit
~/.local/share/applications/mimeapps.list.
Is this really the behaviour we want ?
