Unfortunately I forgot to mention the problem occurs both from my home 
network and via my work network (which I could easily have believed was at 
fault - they've messed with it a lot recently). The ~~~ linux box above 
connects via my home network but I have an aix box at work that also 
connects successfully whereas work cygwin (that's on XP) fails in the same 
fashion as my original post. 

I'm not sure about checking the locale's passed? None of the windows boxes 
have anything other than en_US/en_GB installed though.

No change I'm afraid..
ssh -vvv -i ~/.ssh/ point duplicating the original output. Fwiw there is only a DSA key on 
all these boxes.
