No camera view in WebUI

When I load the WebUI script, the camera preview does not show. I get a broken image. The controls still work, but nothing from the camera.

In the terminal I get this error:

Exception happened during processing of request from ('', 63210)
Traceback (most recent call last):

if sendFrame != None:

it is repeated over and over.

This is a problem we have seen before, it can be fixed easily :)

Open the script in a text editor and change the lines with

!= None


is not None

This should be on lines 178 and 232.
