I'm doing some compositing in Houdini. However, if I try to view a frame where the image Houdini tries to fetch is currently rendering, Houdini freezes and gives me the error:

/*file location*/beauty_Layer.29.tif: Not a TIFF file, bad magic number 0 (0x0).

This keeps repeating in my terminal over and over until the frame is finished rendering, or I replace it with a completed rendered frame. Then Houdini starts responding again and works just perfect. Anyone got an idea on how to fix this?

And not to have incomplete sequences in my composite is not really an alternative due to that I'm doing lots of test renders and development at the moment.

Thanks.
