Unbuffered Query error with product attachments

[ukbaz]

Trying to add or edit product attachements gives the following error:
Cannot execute queries while other unbuffered queries are active. Consider using PDOStatement::fetchAll(). Alternatively, if your code is only ever going to run against mysql, you may enable query buffering by setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute.
DELETE FROM ps_product_attachment WHERE id_product = 412

It is impossible to change/edit attachments
Is there a fix for this?
