Judging from a search on the mailing list, the problem is very typical
when publishing from an old to newer instance.
If this is the case, check out
http://magnolia.sourceforge.net/install/upgrade.html
Then search the lists:
http://gmane.org/find.php?list=magnolia
If no solution is found, then it might be on time to file an issue in
Jira (first search Jira for similar issues).
