I had install base_synchro module in my openerp 7. But, I can synchronize my DB because of this error.

Server Traceback (most recent call last): File "/opt/openerp/server/openerp/addons/web/session.py", line 89, in send return openerp.netsvc.dispatch_rpc(service_name, method, args) File "/opt/openerp/server/openerp/netsvc.py", line 292, in dispatch_rpc result = ExportService.getService(service_name).dispatch(method, params) File "/opt/openerp/server/openerp/service/web_services.py", line 626, in dispatch res = fn(db, uid, params) File "/opt/openerp/server/openerp/osv/osv.py", line 188, in execute_kw return self.execute(db, uid, obj, method, *args, *kw or {}) File "/opt/openerp/server/openerp/osv/osv.py", line 131, in wrapper return f(self, dbname, args, *kwargs) File "/opt/openerp/server/openerp/osv/osv.py", line 197, in execute res = self.execute_cr(cr, uid, obj, method, args, *kw) File "/opt/openerp/server/openerp/osv/osv.py", line 185, in execute_cr return getattr(object, method)(cr, uid, args, *kw) File "/opt/openerp/server/openerp/addons/base_synchro/wizard/base_synchro.py", line 254, in upload_download_multi_thread threaded_synchronization.run() File "/usr/lib/python2.7/threading.py", line 504, in run self.__target(self.__args, *self.__kwargs) File "/opt/openerp/server/openerp/addons/base_synchro/wizard/base_synchro.py", line 248, in upload_download 'body': summary, File "/opt/openerp/server/openerp/osv/orm.py", line 4434, in create cr.execute('insert into "'+self._table+'" (id'+upd0+") values ("+str(id_new)+upd1+')', tuple(upd2)) File "/opt/openerp/server/openerp/sql_db.py", line 161, in wrapper return f(self, args, *kwargs) File "/opt/openerp/server/openerp/sql_db.py", line 226, in execute res = self._obj.execute(query, params) ProgrammingError: can't adapt type 'browse_record'

I'm still new in this openerp. Can anyone guide me please?
