I deleted my SU2LUX installation and to use the one in the repository, but the error doesn't show up.
Could you please write which Sketchup version you are using as well as which operating system?

I don't use yafaray, but it would be helpful if you could reproduce the error and copy the console output, just to understand what's happening under the hood.
