This was a useful comment as I was doing something similar at the same 
time as Milton. I thought it worth mentioning that I found that when 
using sp0.9-2 I needed to fix the function spixdf2kasc in order to get 
sp data into the adehabitat kasc format.

The line that reads  ka <- as.data.frame(attr(sg at data, "att"))

should be changed to

ka <- sg at data

Please try:

ka <- as(sg, "data.frame")

Indeed, it ought to have been that before, then the 2.3.*/2.4.* change in 
how S4 classes are represented would have been hidden. Using coercion and 
access methods is much more robust than grabbing internal bits of objects 
(which are subject to change).
