Reason: [Errno 13] Permission non accordée: ‘None’

[Éric Thiéry]

Hello.
I have reinstalled Qarte on my PC (after switching from Ubuntu 12.04 to 14.04 LTS).
I did it the same way I had done it before, but now, when I want to download a video, I’ve got a window that spell: ‘Qarte is unable to create the folder “None”. Reason: [Errno 13] Permission non accordée: “None”.’
Where did I go wrong (if I did, but I doubt it)?
Could you help me to fix this?
I thank you in advance for your prompt answer.

PS: If you are French…
Vous pouvez toujours me répondre en français. Merci d’avance.

Relancez qarte, ouvrez le menu Options > Options et vérifiez les chemins des deux dossiers de vidéos.
