Error in plugin when using readScore()

batch_convert.qml has this interesting info:

thisScore = readScore(fileFullPath, true);

            // Make sure we have a valid score
            // Rem: MS fails a reading a score ("readScore" above) if the score is already opened. 
            // => So we check if a score with the same path is already opened.
            if (!thisScore) {
                console.log("Failed to read "+fileFullPath+".\nChecking if it is already open.");
                var opened=scores;
                for(var i=0;i Checking if curScore is this file: "+score.path);
                    if (score.path.toLowerCase()===fileFullPath.toLowerCase()) {
                        thisScore=score;
                        isCurScore=true;
                        break;
                    }
                }
                console.log("==> And it "+((!thisScore)?"is not":"is"));
            }
