[R] Trouble loading "saved" Rdata

[Joshua Wiley]

Steven,

I have exited my R session and restarted and I can load the file
without issue.  I have also tried loading the saved data on some older
versions of R (2.10.1 and 2.11.0) and Windows (XP).  Have you tried
recreating the test object, ensuring that it is not NULL itself,
resaving it, and then see if loading it works better?
