Everything says (orbit_small_demarshal): assertion failed

[Core <core enodev com>]

I've rebuilt garnome 0.21.2 on redhat 8.0 many times cleanly, and still
have this wierd problem:

** ERROR **: file orbit-small.c: line 415 (orbit_small_demarshal):
assertion failed: (ret != NULL)
aborting...

Just keeps printing over and over. I'm using:
gcc version 3.2 20020903 (Red Hat Linux 8.0 3.2-7)

My gar.conf.mk is attached.

I've run things in a debugger, here's that (attached:
gnome-about-gdb.txt)

Does this mean it's a libgconf thing?

#GARCHIVEDIR = /home/jdub/src/cvs/gnome/garnome/DOWNLOAD

# These are the standard directory name variables from all GNU
# makefiles.  They're also used by autoconf, and can be adapted
