I saw this same thing yesterday with shuffle nodes. At some point the
script started saving under the syntax you mentioned (in {rgba.red
rgba.green rgba.blue rgba.alpha}, and the script broke. Not sure if it
is related to the channels though, but redguard is present, as was
rgba.beta (which is the main one that is in a lot of our gizmos).
Funny thing about rgba.beta is that you don't seem to be able to
create this channel through the interface (you get a  'Can't change
built in Layer' error), but you can do it through python:

nuke.Layer("rgba",['rgba.red', 'rgba.green', 'rgba.blue',
'rgba.alpha','rgba.beta'])

Maybe something about it is confusing nuke and corrupting the scripts?
