Changing report type from 'pdf' to 'odt' results in broken reports

[Antanas L]

Changing type of OpenERP default reports from 'pdf' to 'odt' results in broken reports

Using OpenERP Server 7.0:
    Install db with demo data
    Install module Sale
    In Settings > Technical > Actions > Reports > Quotation / Order (sale.order report)
    Edit "Report Type", make it 'odt' instead of 'pdf'
    Print Sale Order/Quotation report

The resulting report in .sxw format is rendered incorrectly:
    Layout/design is broken: no header image, different page styling
    some tags are not rendered to values, but displayed as rml tags:
        Fax : [[ (o.partner_id.fax) or removeParentNode('para') ]]
        [[ o.state in ['draft','sent'] and removeParentNode('para') ]] Order N° SO007
        and more...

Result of same nature is observed if repeated for account.invoice , stock.picking.out reports
