Tamas sent me a copy of the bad file, and I've got a workaround:

The problem is an object called .SavedPlots.  It was produced by the 
Windows graphics device when it was recording the history.  It can't be 
loaded into R 3.0.0, because some of the internal organization of things 
has changed.

The workaround is to restart 2.15.3, load the workspace, then


and save the workspace.  After that things should be fine.

I'll try to get something in place in R-patched so that this doesn't 
cause the whole .RData load to fail.
