It is odd.

Here's how it could happen:

>>> a = []
>>> a.append(a)

>>> id(a)
135070976

>>> id(a[0])
135070976

Let's try printing this:

>>> a
[[...]]


The list has a pointer to itself.  I'm not sure if this is the same
problem you're seeing, but you might poke around to see if you're
accidentally using some list instead of some list[some index].
