Hey, thanks for the bug report. It's not immediately obvious to me what's breaking here. Did you ever figure this out?

I managed to solve it by replacing this code in django.templates.base: `class NodeList(list):

def render(self, context):
    return SafeString("".join([node.render_annotated(context) for node in self]))`

with this: `class NodeList(list):

def render(self, context):
    return SafeString("".join([node.render_annotated(context) if isinstance(node,Node) else node for node in self]))`

I am sure there has to be some other way, without messing with the django installation
