I hacked MyTempalte class again to solve this bug.

main2.py:

    import tenjin
    from tenjin.helpers import *

    class MyTemplate(tenjin.Template):

        def add_stmt(self, buf, code):
            if buf:
                s = buf[-1]
                #if s and s.isspace() and s.find("\n") < 0 and len(s)

    if __name__ == '__main__':
        import sys
        if len(sys.argv) < 2: raise "template name is required."
        template = MyTemplate(sys.argv[1], indent=2)     # change
indent width to 2
        #tenjin.Engine.templateclass = MyTemplate
        #engine = tenjin.Engine(cache=False, indent=2)    # change
indent width to 2
        #template = engine.get_template(sys.argv[1])
        print(template.script)

result:

    $ python main2.py ex2.pyhtml
    _buf.extend(('''<div>
      <div>\n''', ));
    if True: ## dummy
      if True: ## dummy
        if foo:
          _buf.extend(('''    foo\n''', ));
        #end
        _buf.extend(('''  </div>\n''', ));
      if bar:
        _buf.extend(('''  bar\n''', ));
      #end
      _buf.extend(('''</div>\n''', ));

This solves the bug, but notice that this hack inserts
a number of dummy if-statements.
So you may not prefer this hack.

I think that it is very hard to control indents accurately
in Tenjin approach. To controll them, it is necessary to
parse Python statements and detect block correctly, like
Mako or Django does. But it makes Tenjin more complex and
heavy, so I wouldn't do that.
I'm sorry but I recommend to compromise at some level.
