Okay, solved the problem. You are correct, I had different id_rsa keys on the two machines (I thought that they were synced, between my machines, but there are not, which is probably a good thing as it happens).
I thought I might have got my pairs mixed up (so I had an unmatched public/private pair), but that wasn't true. The, for me, unexpected thing was that I *had* checked my public key against the only on savannah on my work machine; and, indeed, they were the same, for the first 60 or so characters. Rather a surprise to me; I assumed that public keys were (effectively) random, and checking the start should have been enough. Anyway, all fixed now. Sorry for the time waste, and many thanks!
