Gnome applications seg-faulting at startup

[Jeff Rugen <jrugen primenet com>]

I am getting a segmentation fault when I try to run any of the gnome
applications I'm trying to run.  The details I list below are from trying to
run gnome-session, but gnapster (compiled by myself), panel, gnome-wm, and
gmc all give same results.

The window manager is already running when I try these, but I get a seg
fault with an old line of:

    exec gnome-session & enlightenment

in my .xinitrc.

The segmentation fault seems to occur right as the program starts executing,
so its quite possible that the problem comes from my platform somehow.  In
that case, probably the best advice would be help in tracking down the
problem further.  What follows is a list of related RPMs that I have
installed, my platform and OS, and some info about the gdb backtrace and
strace output. Any help in tracking this problem down further would be
great.  Thanks.

I'm using the following RPMS for Linux/PPC (Motorola Powerstack -- PReP
workstation)
