yaml.load("") raises an exception

With the latest PyYAML (3.04):

$ python
Python 2.4.4 (#2, Oct 19 2006, 23:03:48) 
[GCC 4.1.2 20061007 (prerelease) (Debian 4.1.1-16)] on linux2

>>> import yaml
>>> yaml.load("")
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/usr/local//lib/python2.4/site-packages/yaml/__init__.py", line 66, in load
    return loader.get_data()
  File "/usr/local//lib/python2.4/site-packages/yaml/constructor.py", line 38, in get_data
    return self.construct_document(self.get_node())
  File "/usr/local//lib/python2.4/site-packages/yaml/composer.py", line 23, in get_node
    return self.compose_document()
  File "/usr/local//lib/python2.4/site-packages/yaml/composer.py", line 35, in compose_document
    node = self.compose_node(None, None)
  File "/usr/local//lib/python2.4/site-packages/yaml/composer.py", line 52, in compose_node
    anchor = event.anchor
AttributeError: 'NoneType' object has no attribute 'anchor'

I think this is a bug - at least it should raise a yaml.scanner.ScannerError?, like yaml.load("'") does, and then it can be easily catched as a malformed stream. Right now, it's hard to deal with this.

Thanks, Iustin
