This also is my experience (in Linux & MacOS X). The .RData need not be corrupted, but you have "corrupted" your R installation by deleting or corrupting some package using S4 methods (like failed upgrade of a S4 method package). When you start R so that it tries to restore those S4 objects in .RData, you get the error. Renaming or deleting .RData will help, of course. Alternatively, in my case it helped to start R with option --no-restore-data (in Mac when starting R from terminal -- where you are all the time in Linux). Probably it would help to install again the original S4 package. (In my case this happened when I tried Thomas Yee's VGAM and then removed the package.)
