Comment 5 for bug 837143

This bug (#837143) is said to be a re-incarnation of this:

https://bugs.launchpad.net/percona-xtrabackup/+bug/402884

Bug #402884 says it is due to the following MySQL/InnoDB bugs:

http://bugs.mysql.com/bug.php?id=41609
http://bugs.mysql.com/bug.php?id=45638
http://bugs.mysql.com/bug.php?id=45976

The first 2 of those had been fixed, but not the last, 45976.

However, bug 45976 was recently fixed in MySQL 5.1.62, 5.5.22, and 5.6.5.

Is it reasonable to expect that this bug (#837143) can now be fixed?

Or, is the latest 2.0 Xtrabackup built off a newer version where this would not occur?

Or, would the an even older Xtrabackup work fine as long as the user is using a MySQL that contains this fix?
