I have added a comment to a review and now at the end of the review page I
have a stack trace.

I'm using Django and Reviewboard from today SVN trunk.

I have modified the function NodeList.iter_render to print "node" in the following way:

def iter_render(self, context):
        for node in self:
            try:
                 for chunk in node.iter_render(context):
                     yield chunk
            except:
                 f = open("/tmp/rb.debug", "w")
                 f.write("************** NODE ****************")
                 f.write(node)
                 f.close()
                 raise


I got:

$ cat rb.debug
************** NODE ****************
      <tbody class="
chipx86
#2 chipx86 
As discussed in person, this turned out to be a Django bug.

(I need a ThirdParty keyword at some point)

It was probably a Django problem.
I have updated my Django today and now it works.
