I've seen that the problem is fixed in papyon (it was a variable that
wan not initialized to a default value, because of if ... elseif
without an else)

And also this. When I read the log files I thought that butterfly
would have implemented them, but I was wrong: they get forwarded to
butterfly, but then ignored. I've tried to have a look at the code,
unsuccessfully it's too hard for me.
