Dear all,

Starting emacs with "emacs -q -l test test.org". Then press "C-x
]". Emacs will freeze.

"test" and "test.org" are attached.

Tested on GNU Emacs 23.0.0.1 (i686-pc-linux-gnu, GTK+ Version 2.8.20)
of 2006-10-04 running under fedora core 5.

(setq inhibit-startup-message t)
(add-hook 'text-mode-hook
	  (lambda nil
	    (flyspell-mode t)))
(add-to-list 'auto-mode-alist '("\\.org" . org-mode))

    I can reproduce this under Emacs 22, but I have not been able to
    figure out what is causing this, because Emacs hangs so that it cannot
    even be stopped with C-g.
    
    It seems to be caused by links which contain hidden and intangible text.
    
    Don't really know where to go from here.

    Not at all.  Additional info:  This seems to happen when the cursor
    gets into the white space after a link.  Emacs gets stuck in
    accept-process-output' from the ispell process.  That call is wrapped
    into with-local-quit, which may have to do with the fact that this
    cannot be exited with keyboard-quit.
    
    The work ispell is supposed to be looking up is "uk", and the word is
    extracted from the buffer without text properties, so the fact that I
    am using intangible and invisible text properties should not play a
    role with this.  In fact, I have no idea what might be causing this,
    but I don't see how org-mode could be the true reason.
    
    Here is the backtrace from just before the hangup.  When I press "d",
    emacs will get stuck.
