[Zope] cannot import html_quote?

[Lucas Vogel]

I am getting broken products from the Zope website that seem to be breaking 
because they cannot import html_quote. For example, from BookmarkFolder I get 
this:
<snip>
Traceback (most recent call last):
  File "/usr/local/zope/243/lib/python/OFS/Application.py", line 563, in 
import_product
    product=__import__(pname, global_dict, global_dict, silly)
  File "/usr/local/zope/243/lib/python/Products/BookmarkFolder/__init__.py", 
line 35, in ?
    import bookmark_folder
  File

27, in ?
    from ZPublisher.HTTPRequest import html_quote
ImportError: cannot import name html_quote

</snip>

How do I resolve this?

Thanks,
