can't load just saved R object "ReadItem: unknown type 65"

I have run into a problem loading a just saved R object using R-devel. I 
have been saving and loading this particular type of R object for a long 
while and never ran into this problem. I save, then immediately reload 
(to test save) and get "ReadItem: unnknown type 65".

This error is reproducible after logout from server and restart of emacs 
and R.

Below is my output and sessionInfo().

Thanks,
Mark

According to the logs nothing at all has changed in the serialization
code in a month and nothing of consequence for much longer than that.
To track this down we will need a complete, reproducible, and
preferably minimal example.

Best,

Luke, I'll be gone for about 2 weeks but will work on getting you a 
reproducible example when I get back. If this topic comes up with anyone 
else, please copy me on your responses as I may miss it in the 600 
emails I'll have to delete on my return :) Mark
