The patch is there in xfce4-session 4.10.1-ubuntu1. It's possible you've run into some variation of the same bug, or a different bug. Suggest you set XFSM_VERBOSE=1 in .xinitrc (or whatever your setup uses) and then check the debug log in ~/.xfce4-session.verbose-log and follow up to upstream bug https://bugzilla.xfce.org/show_bug.cgi?id=5379 (if it's the same bug, you should see "Client Id = %s send SAVE YOURSELF DONE, while not being in save mode. Prepare to be nuked!" which results in xfwm not being in session any more.
