I cannot reproduce it with emacs-23.3 on Fedora 16... 
I can reproduce it on yesterday's trunk.

I vaguely remember there was some problem with saveplace.el and 
emacs --daemon, something about saveplace.el wanting to chat when
shutting down.  No idea if that's related, and I can't find the
discussion at the moment...
