When unordered_list processes a list with just two items it fails if the second item is not iterable.
Once convert_old_style_list() determines that 'second_item' is not an empty list, it assumes that item is an iterable. That certainly is true for lists, tuples, and strings. However, if the second item is a non-iterable object the code doesn't work. Nothing in the documentation suggests that the unordered_list filter only accepts iterables, so I think this is a bug.
I've attached a patch with an associated test in regressiontests/defaultfilters/tests.py, but am unsure about whether a test is also needed in regressiontests/templates/filters.py.
