I have run several tests and killed Emerald manually, but my Emacs always 
comes back with window decorations.

When Emacs is maximized, the window manager sets _NET_WM_STATE, usually to
 _NET_WM_STATE_MAXIMIZED_VERT, _NET_WM_STATE_MAXIMIZED_HORZ.

When it is restarted it shall look at the NET_WM_STATE and restore it as it 
was before the crash.  If WM_STATE is set to _NET_WM_STATE_FULLSCREEN however, 
you would see the behaviour you are seeing.

Can you do
% xprop | grep NET_WM_STATE

and then click in the maximized Emacs window?  What is the output?

Do you know what version of Emerald you have?  If you run this with for 
example Metacity, do you see the same effect?
