Please use -vvv when reporting bugs. The lower the debug level, the
larger the responsible region of code tends to be. In this case I need a
bit more in order to help.

While you say it seems to be a client issue, my gut response here would
be a server issue, all other things being equal. Have you checked
/var/log/auth.log on the server? It might be worth starting up a server
on a temporary port with the -ddd option to get detailed debugging from
it.

FWIW I use public key authentication all the time, including to a Debian
stable host, and it's working fine for me.
