Content too short when approving content

First I was in the revision history page of a document:
http://www.blincmagazine.com/forum/wiki/Records


Then I clicked on the (approve) link to approve this update. I was forwarded to:

http://www.blincmagazine.com/forum/w...rds?do=approve



but then I get this error:

The update did not get approved however. It is still pending.

If you are still running 2.5.0, please try updating to 2.5.2. We added a few checks for revisions that may not have been compressed correctly.
