DV50 mov files crash

[Selur]

No clue how that could happen.
When I start Hybrid and press the Vapoursynth Preview button I get
---------------------------
Info
---------------------------
Current source has no video!
---------------------------
OK
---------------------------
same when I open a source, press the input button to load a new source, don't select a file (thus clearing the source) and then pressing the button.

But unless you try to encode non existing files that probably has nothing to do with the error.
