Yes!  Sorry I should be clear that this is no problem on the savannah
side.  This is a client-side issue that occurs if you are using a
hardware dongle for the private keys, and using an old GnuPG stack that
doesn't deal with long messages.  The reason this problem never occured
before was that the OpenSSH server in Trisquel 9 on previous savannah
was so old that it didn't even support the features that trigger the bug
on the client side, but the OpenSSH in Trisquel 11 is recent enough to
do so.  The messages sent to the dongle are longer, to add some newer
OpenSSH data packets.

I think this is not a too uncommon client configuration and debugging
the error message is complicated.  It seems several people has spent
quite some time doing that, all arriving at exactly the same GnuPG bug
report eventually, which contain the workaround.  So maybe it will help
someone here related to the Savannah upgrade too.
