I can't speak to resolve the issue proper, but I have run into many issues 
with emacs in --daemon mode dissappearing when trying to open a X frame as
seems to be occuring here.

I resolved them permanently by taking all the stuff that was X specific in the
init such as font and color and ran the .el file off a before-make-frame hook.

I set a simple binary sentinal to make sure that it only ran once.

Never had a problem since. In my thoughts if --daemon has not gathered any 
information on the X environment which makes sense then deferring execution
of configuring X stuff seems to be the only way out for now.

Here is the relevant part of my config in gitweb. Ignore my grail decorations,
the control block is quite simple and explanatory.


It might be useful in that if the workaround succeeds for the initial poster
it could narrow down the specific bits of information that emacs lacks
in --daemon mode.

How to solve it correctly is a bit beyond me, I just have a work-around to
what I think is the problem.
