We are also affected by this bug.
We are currently in progress of updating our servers to 5.1.60 and only on the 5.1.60 machines we see this happen.
Some (experimental) machines are upgraded to 5.5.18 and do not suffer from this problem.
The correct regex chould be fixed by adding the optional "rel":
$var_innodb_version =~ m/1\.0\.\d+-(rel)?\d/
For now we just added the innobackupex option --ibbackup to to our wrapper scripts.
