I have long since filed a bug against the version of Network Manager
which appeared to be causing the problem, but it's evidently very hard
to track down.  Lots of others reported the same behavior, but I
haven't seen it now in several weeks.  And it was not easy to
reproduce, as it seemed fairly random.  The principal evidence was
that there were always repeated attempts to connect to wifi as the
last entry in syslog before the crash.
