CMS Plugins dropdown appears empty

Hi,

I’m using Django==1.6.8, djangocms==3.0.7 and djangocms-text-ckeditor==2.4.3. When open the CK Editor, I see CMS Plugin dropdown as always, but when click on them, the options list appears empty, as show in the picture below.

In settings I have included the following configuration.

CMS_PLACEHOLDER_CONF = {
    'articulo_contenido_1': {
        'plugins': ['TextPlugin', 'PicturePlugin'],
        'text_only_plugins': ['LinkPlugin'],
        'extra_context': {"width":640},
        'name': gettext("Content"),
        'language_fallback': True,
        'default_plugins': [
            {
                'plugin_type': 'TextPlugin',
                'values': {
                    'body':'<p>Lorem ipsum dolor sit amet...</p>',
                },
            },
        ],
        'child_classes': {
            'TextPlugin': ['PicturePlugin', 'LinkPlugin'],
        },
        'parent_classes': {
            'LinkPlugin': ['TextPlugin'],
        },
    },
}

When I comment the CMS_PLACEHOLDER_CONF, all plugins appears in the dropdown normally. I think there is no typo error in this setting. Do you see anything wrong?

I still experience this issue with django-cms==3.1.4 I tried djangocms-text-ckeditor with versions 2.3.0, 2.5.2, 2.7.0 but changing version does not solve the problem.

Downgrade to version 2.3.0 makes that the plugin dropdown works again.
