The handler name is stored as a pascal string in the QT specs (first byte is the length of the string), thus leading to an invalid metadata string export. Also add a second length check based on the first character to avoid overwriting an already specified handler_name (it happens with Youtube videos for instance, the handler_name get masked), or specifying an empty string metadata.
