I'm pretty sure you have a NULL revision in the node_change table. Can you please try the following query on your database:

SELECT rev FROM node_change WHERE rev IS NULL;

Normally, a "trac-admin $ENV repository resync" should fix the issue.

[Christian Boos]

Or it's due to the too old MySqlDb package (see #9983).

Oh, right, for some reason I overlooked that ticket. Closing as a duplicate, then.
