Actually, this is the part of the code that checks for the notebook version

if (orig_nbformat !== undefined && nbmodel.nbformat !== orig_nbformat) {
             var src;
             if (nb.nbformat > nb.orig_nbformat) {
                 src = " an older notebook format ";
             } else {
                 src = " a newer notebook format ";
             }


I attach a minimal example that fails loading.

I have removed the code from profile/static/custom/, and the error is 
not there any more. OK, so you would classify this as a glitch in 
codemirror. I will try to check this. I'll send an update, once I have 
more on this.
