I'm afraid my answer was more geared towards helping you do
investigations (if you're inclined) or get more detailed info from the
ext4 developers.

As far as what to do next, Jim Kinney has some good practical advice.
I believe he is saying that if your FC13 box doesn't have a kernel
that has this bug, then don't worry about running FC13 for fear of
data corruption... worry because it's old.
