The query on line 31 of workflow.pages.inc includes the clause, "ORDER BY hid." There is no such column in the workflow_node_history table.

The table workflow_node_history has the 'hid' column on it in the schema in workflow.install. If you are still seeing this issue, you may need to uninstall/reinstall Workflow as it seems like your tables didn't get fully installed.
