The code you give works fine. It does not show the error you say it does. 
Please test your code before posting and ensure it actually fails the way 
you expect.

It is perfectly fine to use multiple inheritance in the way you show. 
Here is an even simpler example:

py> class Spam(object):
...     pass
... 
py> class Ham(list, Spam):
...     pass
... 
py> 
py> h = Ham([1, 2, 3])
py> 

And no exception is raised.
