Re: org-clock-in fails sometimes with prefix arg

[Bernt Hansen <bernt@norang.ca>]

This happened again this morning.  I'm not (to my knowledge) actually
using the org-clock-persistence stuff but it is active.  Again I have an
'org' buffer which is a dired entry at the end of my clock history list.

I'm going to try a few things

  - restart emacs and see if I can reproduce what causes this

  - turn off the cock persistence settings and see if this problem goes
    away (don't expect a report on that for at least a week)
