Re: Finding .desktop file and application info

[Osmo Antero <osmoma gmail com>]

Btw:
Totem (GNOME `s Video Player) has very similar problem.
It «lies» about its .desktop file name. It says "totem" instead of
"org.gnome.Totem".
My app asks for it via DBus/MPRIS2 and gets wrong data.

$ locate -i totem | grep ".desktop"
/usr/share/applications/org.gnome.Totem.desktop

It is hard to co-operate on the Desktop when apps do stick to the damn
rules.

Boa noite,
