The contents of NEWS have nothing to do with this, I think.  The
problematic characters do not come from NEWS, they come from Edebug
trying to display a numeric result as a character.  At least this is
my current theory...

Right, now I see it as well (except that, the 1st time I use C-x n n,
I need to answer the question about it being disabled; the crash
happens the next time I invoke C-x n n).

So you can forget about all my requests regarding various values in
the crashed frame.

Thanks.
