How to pass a string to a custom filter?

[Mirto Silvio Busico]

Hi all,
I'm trying to pass a string to a custom tag to create custom breadcrumbs.

I'm using as a base the snippet at 
http://www.djangosnippets.org/snippets/656/
and using the documentation from 
http://docs.djangoproject.com/en/dev/howto/custom-template-tags/

But it seems that I'm not able to pass the URL as a string.

In ... zsite/ancore/templatetags/mytags.py (zsite is the django project 
directory) I have:
==============================================================
#!/usr/bin/python
# encoding: utf-8
from django import template
from django.utils.safestring import mark_safe
from django.utils.translation import ugettext
from django.template.defaultfilters import stringfilter
from types import *

register = template.Library()

@register.filter(name='dovesono')
@stringfilter
def dovesono(aurl):
  
   bc = u''
   parti=aurl.split('/')
  
   bc= u' - %s - len=%d char= %s %s' % 
(parti[0],len(parti),aurl.count('/'),(type(aurl) == StringTypes))
     
   for i in range(len(parti)):
      bc=bc+' &raquo '+parti[i]
  
   return mark_safe(bc)
==============================================================

In the calling template I have:
==============================================================
{% block breadcrumbs %}
    {% load mytags %}
    <div class="breadcrumbs">
    {{ request.get_full_path|dovesono }}
    </div>
{% endblock %}
==============================================================

and the generated html is:
==============================================================

        <div class="breadcrumbs">
     -  - len=1 char= 0 False &raquo  
    </div>

==============================================================

So (type(aurl) == StringTypes) is evaluated False

What I'm doing wrong?
What is the method to pass the actual url to a filter as a string?

Thanks
    Mirto
