In my test environment I cannot confirm this.
But you can make some tests. Edit upload.php and try to print the value of $genre right after the database-insert like this:
echo "Genre: ".$genre;
If there is no value printed you can add the following code right before the database-insert:
$genre = 'nameofthecategorywhereallbaduploadswillbeplaced';
And if you want to be sure, that you will see that there are mis-leaded uploads insert the following line right after the above:
$approved = 0;
Sorry for your problems.
