When iterating over the list of filters to honor them [1], the method remove elements from that list at the same time [2].
This way, not all filters are honored since the internal idx used by python is not aware of the removal while iterating. The following example code exposes this behavior:
a=[1,2]
for b in a:
print b
a.remove(b)
It prints 1 and the list ends with element 2.
