Just tried Gamine. Some things still need fix.
It doesn't start from menus. I tried to change it's desktop menu with a few additional lines found elsewhere, but no success, the problem doesn't seem to come from there.
I looked into pcmanfm applications section, and when I do a right-click/open on the icon I get this message : "L'exécution du processus fils « /usr/local/bin/gamine e» a échoué (Aucun fichier ou dossier de ce type)". Something looks for it in /usr/local/bin. (why ?)
When I start from the console, it works and it now has the sound. Progress !
But no pencil, and the console output states :
*** error: /usr/share/gamine/pencil.png does not exists***
*** error: /usr/share/gamine/gamine.png does not exists***
I saw the pencil.png image at the root of the sources archive the other day. Don't you want the pencil to be included ?
