At this point, I am not convinced we have a problem with what will turn
out to be 8.4-RELEASE.

There have been several attempts to ensure the upgraded version is
actually 8.4-RC3 (and again, 'uname -a' is not provided in this
email...).

I find it very hard to believe that we have exactly one fxp(4) user
upgrading to 8.4-*.

I'd really like to make sure that this is not an issue that will affect
an uncountable number of users, but truthfully, at this point have to
consider it a local configuration problem.
