[Twisted-web] Nevow: returning defer.succeed() from the data_* or render_* method

What's wrong with the code below?

from nevow import tags as T, loaders, rend
from twisted.internet import defer

def simple(ctx, data):
    return defer.succeed("Hello, world!")

class Simple(rend.Page):
    docFactory = loaders.stan(
                    [T.li[ T.invisible(render=simple) ] for _ in xrange(1000)]

I get an exception

"exceptions.RuntimeError: maximum recursion depth exceeded"

rendering this page. It's the defer.succeed what causes this error; if I
return bare string, all is ok.

Thanks in advance.
