I installed fresh on a development box and I saw the exception
below on the mainpage with Firefox where the RefreshHomepage
element should be.

On my production box, my perl has Apache::Session 1.81_01

On my devel box, my perl has 1.84 which includes error
handling.

After re-logging in two or three times, the exception goes away.

With Opera I can't produce this exception.

I also cannot produce the exception when I run the devel Apache httpd
with -X.

My WAG is that Firefox and IE are doing parallel requests
and triggering an Apache::Session::Lock::File deadlock which is
somehow forcing the session to be invalidated.

Most RT users probably use MySQL and Postgres and RT defaults
to using those databases for session management so won't stumble
across this bug.
