It would look more useful if I were actually experiencing a freeze.
I'm not.  To repeat: when I reboot, the first X gnome login aborts
during the playing of the welcome sound, and takes me back to the
login screen.  Almost always the subsequent identical login works
fine.  Once I had to try three times, I think.  All operations after
that are normal.

Judging from the help in the indicated thread, it may be time for a bug report.
