I've got a problem when uploading one particular mp3 file using Media Library. I get an error message (in french that says: "Une erreur est survenue lors de l’envoi. Veuillez réessayer plus tard.").
I can't figure out why this happens with this particular file. The file is not heavy, the name has nothing particular... I've checked the file using an offline media player and it works OK.
I tried several times with no luck.
