Starting Emacs fails with the error:
Warning (initialization): An error occurred while loading `/home/juri/.emacs':
error: Attempt to modify read-only object
To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file. Start Emacs with
the `--debug-init' option to view a complete error backtrace.
Starting Emacs with the `--debug-init' option displays:
Debugger entered--Lisp error: (error "Attempt to modify read-only object")
delete(("\\`\357\273\277" . utf-8-with-signature) (("\\`BABYL OPTIONS:[ ]*-\\*-[ ]*rmail[ ]*-\\*-" . no-conversion) ("\\`\376\377" . utf-16be-with-signature) ("\\`\377\376" . utf-16le-with-signature) ("\\`\357\273\277" . utf-8-with-signature) ("\\`;ELC" . emacs-mule)))
(setq auto-coding-regexp-alist (delete (rassoc ... auto-coding-regexp-alist) auto-coding-regexp-alist))
The reason of this error in .emacs is the lines that remove a match
for `utf-8-with-signature' from `auto-coding-regexp-alist' that allows
to always display the BOM (Byte-order mark signature) to be able
to remove it without the need to visit files literally:
(setq auto-coding-regexp-alist
(delete (rassoc 'utf-8-with-signature auto-coding-regexp-alist)
auto-coding-regexp-alist))
Before yesterday there were no problems with this.

This is mine, too aggressive use of purecopy.
auto-coding-regexp-alist needs to be changed like this:
(defcustom auto-coding-regexp-alist
(mapcar (lambda (arg) (cons (purecopy (car arg)) (cdr arg)))
'(("\\`BABYL OPTIONS:[ \t]*-\\*-[ \t]*rmail[ \t]*-\\*-" . no-conversion)
[....]
I'll check it in when I get a chance. If it's in your way, please feel
free to do it earlier.
