Good catch! I was just trying to get something to work, but it seems like you found another bug. I am now checking if it is None:
No, I think these latest changes don't do anything. The error message says: you are storing in the rb_flags attribute something that is sometimes a dict, and sometimes an instance of W_Root. Check if there is somewhere else a subclass of W_Root with its own rb_flags attribute which would be set to a W_Root. Then you'd get a crash using that subclass, also untranslated, simply because 'rb_flags' is supposed to be two different things. To be on the safe side, you should change the name of the attribute in W_Root from rb_flags to something much more obscure like "_frank_rb_flags". A bientôt, Armin.
