Comment 8 for bug 26590

I've opened a bug on gnome-menus upstream:
http://bugzilla.gnome.org/show_bug.cgi?id=323476

gmenu_tree_directory_get_contents(), which is used by the open with dialog,
doesn't return "NoDisplay=true" desktop files. According to IRC discussion
that's a feature though and alacarte should use <Exclude> rather creating a new
.desktop for this. There is probably a timestamp issue too though, after moving
/usr/share/applications away and back those entries are not listed by the
function neither
