I cannot reproduce this bug here.

Does it happen even if you connect to the machine and logout immediately?

Which ssh client do you use? And could you try to reproduce the problem using
various ssh clients?

Also you could try to rebuild the openssh-4.0p1-2 from Fedora Core Development
and install it on your machine and try if it solves the problem or not.
