Just now, I have discovered (with rev. 100032) that Emacs does not like
any more this:
(setq-default bidi-display-reordering t)
in my initialization file: it aborts!
To reproduce: add the above to .emacs (or to .emacs.d/init.el) file;
then 'short circuit' the desktop file, if any. For example renaming it:
mv desktop desktop.save
In this way Emacs should starts with the 'scratch' buffer.
Then
$ emacs &
aborts. If you want to use the desktop file, after Emacs is started, you
should switch buffer up to the 'scratch', for example clicking with
mouse-1 on buffer name in the mode line: then switching from 'Messages'
buffer to scratch' causes Emacs to abort.
In short, Emacs does not like the above (setq...) in .emacs and the
'scratch' buffer.
I have verified this both on GNU/Linux Kubuntu 9.10 and on Cygwin.
Ciao,
Angelo.
