[O] org-open-at-point calls visit-tags-table ?!?

[David Masterson]

I have various Org files with internal hyperlinks of the form
[[#mylink][My Link]] that should point to a header with the appropriate
CUSTOM_ID property that I've setup.  For some reason that I can't figure
out, when I call org-open-at-point (C-c C-o) on the link, it tries to
open a tags table (visit-tags-table) which is not what I expected.  Does
anyone know why?  I'm suspicious that I have a conflicting MELPA package
for Org of some sort, but I don't know where to start to debug this.
What's the safest way of turning off the packages in .emacs.d/elpa?  Can
I just move the elpa directory for testing purposes and then move it
back later?
