Minor visual problem in django admin (and correction)

[deltoide]

When I use callables in the 'list_display' property of the Admin class, the header columns (names of those properties) are not displayed correctly (see screenshot here: ​http://bit.ly/1bVz1R).
After investigating a little I found that it was because a missing property (class_attrib) of the header object:

This correction works for me (file: admin_list.py in django/contrib/admin/templatetags/, line 116):

            # It is a non-field, but perhaps one that is sortable
            admin_order_field = getattr(attr, "admin_order_field", None)
            if not admin_order_field:
                yield {"text": header,
                       "class_attrib": "", # line added
                       }
                continue

Small precision: the problem is only there if TEMPLATE_STRING_IF_INVALID is set to something other than .

Then it's a dupe of #3579.
