You are wiping out all of the default options with that approach.
Actually, I think it hid the options() function.
Since I was doing this at the RGui and became concerned that it
appeared I no longer had any options, I restarted. Could I have saved
time by just executing rm(options)?
Try (after restarting R to get the other options back to what they
should be):
op=options() # so you can reset back to baseline
options(error=utils::recover) # do not think the "utils::" is needed
Not if you run it in the console, but it is needed in .Rprofile.
Because it might be executed before the loading of the default packages?

Saving the old option could be done as
olderror <- options(error=utils::recover)

Duncan,
I've pared down my .Rprofile so that it has just the options
line, started R
from terminal (instead of using ESS-emacs) and I still have the
problem. Am
I specifying the options incorrectly? I believe I took this
directly from
the help page.
Not what the examples look like on my machine.
See my output of .Rprofile, the code example that doesn't
work as we think it ought, and my sessionInfo(). Thanks, Mark
