The Action link in the menu is defined in the Action tab for the portal_type. 
For some reason the default for View is not defined and as a result it uses 
aquisition to fill in the closest defined index_html web page. To fix the 
problem just define a view Action for the Folder type. Go to the Action tab 
in  /YourCCMFSite/portal_types/Folder and create a name for for the View 
Action. I used "folder_view_form".

Then create a Python script called  
/YourCMFSite/portal_skins/custom/folder_view_form   

Here's a very broken script, but it will get you started in building something 
that will display the contents of the folder. (I'd finish it before posting, 
but they will be turning power off in our building in about 20 minutes and 
I've got to power down.)

from Products.PythonScripts.standard import html_quote
request = container.REQUEST
RESPONSE =  request.RESPONSE

print container

print traverse_subpath

print "contains :%s:" % container.contentIds()


#print container.REQUEST
# Return a string identifying this script.
print "This is the", script.meta_type, '"%s"' % script.getId(),
if script.title:
    print "(%s)" % html_quote(script.title),
print "in", container.absolute_url()
return printed
