Package: python-html5lib
Version: 0.90-2
Severity: wishlist

If I pass a treebuilder that doesn't exist to parse(), the exception message is
not very helpful:

html5lib.parse(sys.stdin, treebuilder='lxm;') # <-- typo
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/pymodules/python2.7/html5lib/html5parser.py", line 37, in parse
    p = HTMLParser(tb, namespaceHTMLElements=namespaceHTMLElements)
  File "/usr/lib/pymodules/python2.7/html5lib/html5parser.py", line 68, in 
__init__
    self.tree = tree(namespaceHTMLElements)
TypeError: 'NoneType' object is not callable


It would be nice if html5lib could throw an exception with a meaningful error message in such case.
