Nuke Python error


#1

I am building a large nuke script from smaller template scenes using nuke.nodePaste(scene_file)

It all worked fine until I started seeing this error:
Knob:font_size_values. Setting knob values from validate is not supported and may cause unexpected behaviour
I get this for every text node in the scene.

I tried calling textNode.forceValidate() but that changes nothing.
Nuke gets so far through rendering the scene and crashes, BUT if I save the scene and load it with the GUI (the big script is compiled in python) everything works.

Anyone have any idea what this means? Anyone seen this before?
Any pointers greatly appreciated

Cheers
