This bug has 2 manifestations somehow depending if you use an MySQL DB or only the build in database
Steps to reproduce:
1. Upload a video use umlaute "äöü" or probably other non ASCII characters in the "presenter" field.
2. The video gets uploaded the confirmation screen contains the right presenter name.
With internal database: the umlaute in the presenter name are replaced by "?" AFTER the initialising step. During INITALIZING the Presenter name is still correct. The processed video is not playable.
With the MySQL database the Job gets stuck in INITALIZING and I get the error message in the code snippet.
