Error with custom widget in placeholder

If I specify a custom widget in {% placeholder %} tag like this

{% placeholder my_field with myapplication.MyCustomWidget %}

I get the following error in Page Edit form:

Traceback:

Exception Type: TypeError at /admin/pages/page/3/
Exception Value: Item in ``from list'' not a string

The problem is that module_name and class_name variables are unicode
objects while __import__ expect them to be strings. I attach the patch to
fix that.
