[R] .Rprofile is being executed twice

[Dan Tenenbaum]

Hi,

After updating to R 2.7, my .Rprofile executes twice on startup. I 
confirmed this by putting in the following line:
print("starting .Rprofile...")   

When I start R, I see:
[1] "starting .Rprofile..."
[1] "starting .Rprofile..."

This seems like the obverse of the following FAQ:
http://cran.r-project.org/doc/FAQ/R-FAQ.html#Why-did-my-_002eRprofile-stop-working-when-I-updated-R_003f

But in my case .Rprofile is working, just working twice as much as it 
should.

Even if there is nothing in my .Rprofile except that print() statement, 
it still executes twice.

What could be causing this?
Thanks
Dan
