Which package should it be filed against?

I don't think it is anything to do with ssh-add itself, which is part of
openssh-client.  This looks like something else misbehaving.

I just tested in Ubuntu 13.04 and the problem is the same there, too.
I'm not sure why it was not triggered until recently.  I don't have
Kubuntu or Xubuntu around to test in.
