If view_type==tree, reports are not available

Hi!
The right toolbar and the report menu options aren't available if the view_type==tree. This is a problem for example with the Chart of Accounts wizard, because it opens this action:

        <record id="action_account_tree" model="ir.actions.act_window">
            <field name="name">Chart of Accounts</field>
            <field name="res_model">account.account</field>
            <field name="view_type">tree</field>
            <field name="view_id" ref="view_account_tree"/>
            <field name="domain">[('parent_id','=',False)]</field>
        </record>

and for this view the Account Balance and General Ledger reports should be available as they are in the other clients.

Thank you in advance.
