to my surprise, it does work on my other machine!

<snip>
my.data <- data.frame (var=as.numeric (rep (NA, 1)), var1=as.numeric (rep (NA, 
1)), var2=as.numeric (rep (NA, 1)), var3=as.numeric (rep (NA, 1)), 
var4=as.numeric (rep (NA, 1)))
.rk.get.structure.global ("my.data")

row.names (my.data) <- NULL

my.data[["var"]][1] <- NA

attr (my.data[["var"]], "levels") <- NULL

my.data[["var1"]][1] <- NA

attr (my.data[["var1"]], "levels") <- NULL

my.data[["var2"]][1] <- NA

attr (my.data[["var2"]], "levels") <- NULL

my.data[["var3"]][1] <- NA

attr (my.data[["var3"]], "levels") <- NULL

my.data[["var4"]][1] <- NA

attr (my.data[["var4"]], "levels") <- NULL


.rk.get.vector.data (row.names (my.data))

.rk.set.vector.mode(my.data[["var"]], as.factor)
attr (my.data[["var"]], "levels") <- NULL

my.data[["var"]][1] <- NA


attr (my.data[["var"]], "levels") <- c ("one", "two")
my.data[["var"]][1] <- NA


my.data[["var"]][1] <- "one"

.rk.data.frame.insert.row (my.data, 2)
row.names (my.data) <- NULL

my.data[["var"]][2] <- "two"


my.data

  var var1 var2 var3 var4
1 one   NA   NA   NA   NA
2 two   NA   NA   NA   NA
</snip>

here's some details on the system where it works:

i'll post details on the failing one later (it's a 64-bit system, that much i 
can tell at once). i also tried this on our mac -- i can fully confirm the 
report, the levels are not even stored in the first place, nothing shows up in 
the command log at all when you try to set levels.

but try this:
 1. create my.data
 2. turn "var" into a factor
 3. in the R console:
> my.data
    NA var1 var2 var3 var4
1 <NA>   NA   NA   NA   NA
Warnmeldung:
In format.data.frame(x, digits = digits, na.encode = FALSE) :
  Korrupter Data Frame: Spalten werden abgeschnitten oder mit NAs aufgefüllt

 4. after just setting the levels ("one", "two"):
> my.data
   var var1 var2 var3 var4
1 <NA>   NA   NA   NA   NA

 5. fill in data:
> my.data
  var var1 var2 var3 var4
1 one   NA   NA   NA   NA
2 two   NA   NA   NA   NA

 6. now remove the levels:
> my.data
  var.NA var.NA var1 var2 var3 var4
1   <NA>   <NA>   NA   NA   NA   NA
2   <NA>   <NA>   NA   NA   NA   NA
Warnmeldung:
In format.data.frame(x, digits = digits, na.encode = FALSE) :
  Korrupter Data Frame: Spalten werden abgeschnitten oder mit NAs aufgefüllt

we suddenly gained a new variable? this is on the working machine -- can you 
reproduce this?
