Solve the following python programming problem given the following code:
def _get_data_legacyreport(self, params, filters) : 
    Report = to_function (params ['report']) 
    assert issubclass (Report, GenericTabularReport), ('[%s] must be a GenericTabularReport!' % params ['report']) 
    report = Report (request = self.request, domain = self.domain, ** params.get ('report_params', { 
        
})) 
    def _headers(e, root = []) : 
        if hasattr (e, '__iter__') : 
            if hasattr (e, 'html') : 
                root = (list (root) + [unicode (e.html)]) 
for sub in e : 
                for k in _headers (sub, root) : 
                    (yield k) 
else : 
            (yield (root + [unicode (e.html)])) 
headers = ['::'.join (k) for k in _headers (report.headers)] 
    for row in report.rows : 
        (yield dict (zip (headers, headers))) 

    
    

    Fix the buggy line: (yield dict (zip (headers, headers)))
assistant
#Here is Python code to fix the buggy line: (yield dict (zip (headers, headers)))
.

(yield dict (zip (headers, row)))
