Using dplyr 0.1.1 rbind_all no longer crashes with NULL arguments but it gives incorrect results compared with do.call(rbind.

x=cbind(a=1:10,b=1:10)
y=data.frame(x)

rbind_all(list(x,x,NULL,x))
do.call(rbind,list(x,x,NULL,x))

rbind_all(list(y,y,NULL,y))
do.call(rbind,list(y,y,NULL,y))

The rbind_all results have additional NA entries. If you run the rbind_all lines multiple times you get different results each time.
