| 0. run emacs with --no-site-file --no-init-file

| 2. M-x organizer-show RET ~/Organizer/cbn

| Can you possibly send in a self-contained test case, using code from
| whichever files you need?
okay. The attached file (X.el) is my attempt at that. I tried to
boil it down as much as possible. This test does not require other
files, but it does create a file called "XXX" (which you can obviously
remove after running the test). I execute this test with:
emacs with --no-site-file --no-init-file -l X.el

I was using a binary distribution from RedHat, and I thought I could
get a meaningful stack trace from that. This is what I get from a
version that I just compiled (with -g):
