Names handling, more likely:
> v <- structure(list("2" = NA), .Names = "2", class = "data.frame", row.names = "2")
> u <- structure(list("2" = structure(1, .Names = "1", .Label = "O", class =

> uu <- structure(list("2" = structure(1, .Label = "O", class = "factor")), .Names =

> rbind(v,u)
2
2 <NA>
1 O
> rbind(v,uu)
2
2 <NA>
1 O
> rbind(u,v)
Error during wrapup: incompatible types
> rbind(uu,v)
2
1 O
2 <NA>
(Notice that the only difference between u and uu is the .Names bit)
