I'm using 23.x pretests and haven't updated in almost a month so mine is probably much older than yours.  I am running 6.28b of org which I think you are too.  Not sure what the issue is.

Greg, I did come across this. Unfortunately, I didn't make a note of
when or where and can't reproduce it this evening.

I have a suspicion, but only a suspicion, that it may have resulted from
a (now fixed) tramp bug in CVS Emacs. I last complied on 15 July. Could
this be a possibility?

[There are gaps in the above logic; I can't figure out why org-link
should work whilst org-note and org-remember bork. I'm clutching at
straws. No idea why it is so fragile.]
