Hello Tito,
Muito obrigado.
Thank you, the call with "kde4-" worked fine.

However,  the "DesktopEntry" value from Amarok/DBus does not contain the
"kde4" part.
Please see the MRIS2-spec:
https://specifications.freedesktop.org/mpris-spec/latest/Media_Player.html#Property:DesktopEntry

My application cannot guess that it must include the "kde4" to get a valid
.desktop file.
I think g_desktop_app_info_new() should also browse all sub-directories,
but is does not.

One possible solutions is this:
The application should find the real location and path of
"org.kde.amarok.desktop".
The "locate" command does the same thing.
My app cannot call "locate" directly because it depends on "sudo updatedb".
I will write my own routine that dives to usr/share/applications/ and its
sub folders.
This is my best shot !

Then the app can call:
GDesktopAppInfo *g_desktop_app_info_new_from_filename(const char *filename);

My very old app is this: (the latest is v3.0.2)

Thanks,
Obrigado e boa noite.
