When I start Emacs (trunk, updated & bootstrapped today), it core
dumps during startup.  I cannot reproduce the crash...

- with `-Q'
- with `-nw'
- when starting it under gdb
- when starting it in ./src

I could trace it down (see strace output below) to
  (load rs-custom-file t t)
in an init file.  When I comment this line, Emacs starts correctly.
`rs-custom-file' is "~/.emacs-custom", but this file doesn't exist:

~$ ls .emacs-custom*
ls: cannot access .emacs-custom*: No such file or directory

> If Emacs crashed, and you have the Emacs process in the gdb debugger,
> please include the output from the following gdb commands:
>     `bt full' and `xbacktrace'.

As I can't reproduce it under gdb, I did:

cvs-HEAD/i686/src$ (cd ..; rm -vf core; ./src/emacs; ls -l core )
removed `core'

Since no one seems to be able to reproduce this, I'm closing the bug.
