UnboundLocalError when calling append_array_item with array_options

What steps will reproduce the problem?
1. xmp.append_array_items(namespace, 'foo', 'bar',
array_options=dict(prop_value_is_array=XMP_PROP_VALUE_IS_ARRAY))
2.
3.

What is the expected output? What do you see instead?
Expected an array to get added to the xmp. Instead, got an UnboundLocalError.
UnboundLocalError: local variable 'options' referenced before assignment

What version of the product are you using? On what operating system?
1.0-rc1. But it looks like the current trunk (r39) has this issue too by
looking at the source. I'm on fedora 10, python2.5

Please provide any additional information below.
The issue looks like a simple spelling error. Here's the patch that fixed
it for me:
