(getenv "HOME") returns nil in X frame

[Eric Hanchrow]

I started Emacs like this (from gnome-terminal):

$ /usr/local/src/multi-tty-emacs/src/emacs -Q -nw

I then typed M-: (getenv "HOME"), and saw "/home/erich" in the echo area -- as I expected.

I then typed M-x make-frame-on-display RET :0 RET, and as expected got a new X frame.

In that new frame, I typed M-: M-p, to re-evaluate the "getenv" form;
this time, instead of seeing "/home/erich" as I expected, I saw nil.

This is bad -- many things depend on (getenv "HOME") working. In
particular, if I type C-x d RET, expecting to get a listing of my home
directory, I instead see a listing of the root directory; and if I
type M-x report-emacs-bug RET, I get an error whose details escape me
at the moment.

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'.
If you would like to further debug the crash, please read the file
/usr/local/src/multi-tty-emacs/etc/DEBUG for instructions.

Thanks for reporting this. I fixed this bug in patch-575; please test.
