Problem unlink record from calendar

[Nicola Riolini - Micronaet]

Hello I have last openerp v.7.0 updated today (standard openobject-addons)
I see this problem in calendar view hr.timesheet but I prefer report a bug (even if I customize inheriting hr.timesheet)

The problem is that: in calendar view, if I unlink a record with the recycle bin icon, openerp pass ids as integer instead of list of ids so I got a generic error (and no record are erased).

I dig into the code and I see that generic error is a "no iterable object error" when I arrive at this point:

/home/thebrush/lp7/openerp/openerp/addons/hr_timesheet/hr_timesheet.py(81)unlink()
for obj in self.browse(cr, uid, ids, context=context): <<<<<<<<<<<<<

obviously because ids is a integer not a list.
My workaround is create, in my module, a override method of unlink:

    def unlink(self, cr, user, ids, context=None):
        if type(ids) not in (list, tuple):
            ids = [ids]
        return super(hr_analytic_timesheet_extra, self).unlink(cr, user, ids, context)

My bug is for ask if, in calendar, is possibile have unlink call with list (usually there's not problems but, as you see, in some modules like timesheet, there a loop based in list of ids).
Thanks (please feel free to change project if the bug is not in correct one)
