I was hoping that this uninformative error was now spurious, meaning 
that my 'fix' indeed only got rid of the error message. However, as it 
seems, the stream is still truncated. I rebuilt the truncation check, 
now with a proper error and disconnect (because the protocol state is 
invalid then).

However, regarding the core of this problem, I am unable to reproduce 
this at my end without access to a FreeBSD system. Could you (or some 
other FreeBSD user) try to dig a little deeper to find out exactly why 
the stream ends prematurely? Alternatively, I would have to install 
FreeBSD somewhere, which will take more time.
