芹菜绑定=True会导致异常

Question

我使用Celery v3.1.19执行一个任务，这个任务调用一个函数，其中一个参数是字典。当bind=True:时，我总是会出现此错误

[2016-01-03 09:33:41,883: ERROR/MainProcess] Task hypervisor.esxi.deploy_esx.imbue_esx[21A2B368B2] raised unexpected: TypeError("imbue_esx() got multiple values for keyword argument 'configuration'",)
Traceback (most recent call last):
  File "/Users/gogasca/Documents/OpenSource/Development/Python/IMBUExApp/venv/lib/python2.7/site-packages/celery/app/trace.py", line 240, in trace_task
    R = retval = fun(*args, **kwargs)
  File "/Users/gogasca/Documents/OpenSource/Development/Python/IMBUExApp/venv/lib/python2.7/site-packages/celery/app/trace.py", line 438, in __protected_call__
    return self.run(*args, **kwargs)
TypeError: imbue_esx() got multiple values for keyword argument 'configuration'

当我看到函数imbue_esx定义如下：

@task(bind=True)
def imbue_esx(
        configuration={},
        job="1",        
        api_call=False,
        cli=False,
        manual_mode=False,
        log_file="",
        **kwargs):

这就是我发送此任务的方式：

 celery.send_task("hypervisor.esxi.deploy_esx.imbue_esx",                                                
                                             kwargs={'configuration': configuration,
                                                   'job':job_ref,                                                      
                                                   'api_call': True },
                                             task_id=job_ref)

我试过这样调用imbue_esx：

celery.send_task("hypervisor.esxi.deploy_esx.imbue_esx",
                                             kwargs={'configuration': configuration,
                                                     'job':job_ref,                                                       
                                                     'api_call': True,
                                                     'cli': False,
                                                     'manual_mode': False,
                                                     'log_file': ""},

甚至从imbue_esx中移除**kwargs，但总是得到相同的错误。有什么想法吗？

调试

我升级到v3.1.19，并在函数imbue_esx中添加了self参数。
