AccessViolationException FileStream (EX9.Texture VLC) + Echo (EX9.Texture Filter)

Hi,
I found AccessViolationException with FileStream (EX9.Texture VLC) + Echo (EX9.Texture Filter).
I will attach sample v4p file.

I saw a message in my console when excepton occurred.

Sorry for Japanese, since my Windows is Japanese.
