Solution is so complicated.

1. Stop using Section View plugin
2. Stop Hudson
3. Backup /user/.hudson/config.xml file
4. Delete config.xml
5. Make upgrade to last Hudson war
6. Start Hudson
7. Upgrade Section view plugin
8. Start using Section View Plugin
9. Stop hudson
10. Restore config.xml from backup
11. Start Hudson

All working! Good luck!
