at(..) uses the index, which is zeroth counted... so you want:

	s.at(buflen - 1);

also, not that it probably really matters, but the check for (*it) shouldn't 
be necessary in your for loop because you know it's origins (the 
QStringList::split above). you are pretty well guarenteed it will be alright.
