I'm not sure what the deal is here, but exiting X does solve the problem.  I didn't try just killing the environment by shutting down the wm and leaving X up, but if I forget and do something like that again I'll try to remember to try it.

Agreed, but I saw someone else was having a similar problem with 9.0 release a bit earlier on a system, and no problem with 8.3.  At least I think that was it.  Hmmm, just looked and there's a firefox-bin.core and an xfce-appfinder.core.  Timestamps look about right for when I did a vty switch.
