Yeah ... not sure if that's what happening (R class relationships/ 
testing is still a bit of a mystery to me), but see:

R> df <- data.frame(a=1:10,b=1:10)
R> is(df)
[1] "data.frame" "list"       "oldClass"   "mpinput"    "vector"

But

R> is(df, 'list')
[1] FALSE

So, in short, I don't know if that's what's happening ... did it fix  
your problem, tho?
