Manage features screen is empty

In my config (d7b2, ctools 7.x-1.0-alpha1, features 7.x-1.0-alpha3) I get the following notices:

* Notice: Undefined index: api in _ctools_features_get_info() (line 212 of /Applications/MAMP/htdocs/drupal-7.0-beta/sites/mori.drupal7.dev/modules/corefunctions/features/includes/features.ctools.inc).

Maybe this helps?

The Notices are not displayed when disabling all CHAOS TOOL SUITE additional options and show´s up again when enabling stylizer:

Had the same problem. After upgrading to D7 beta2 manage features page is empty. My problem was with format filters exported features set. Before beta2 they were stored as numbers in database and now they are stored with machine name http://drupal.org/node/934050.

I have managed to manually change my exported features and fix this. In my_features.info file I have changed

features[filter][] = "Filtered HTML"
features[filter][] = "Full HTML"
features[filter][] = "Plain text"

to

features[filter][] = "filtered_html"
features[filter][] = "full_html"
features[filter][] = "plain_text"

And then in my_features.features.filter changed

// Exported format: Filtered HTML
  $formats['Filtered HTML'] = array(
    'name' => 'Filtered HTML',
    'cache' => '0',
    ....

to

// Exported format: Filtered HTML
  $formats['filtered_html'] = array(
    'format' => 'filtered_html',
    'name' => 'Filtered HTML',
    'cache' => '0',
    ....

and done the same for other two exported filters. After that features module is happy, everything works correctly and I can verify that for now features and strongarm works ok with D7 - I am using all latest dev releases. Just in case I recreated my features again after managed to get features module working.

I know that this is maybe not related to

Invalid plugin module/type combination requested: module stylizer and type style_bases

error, but I had the same error and also one more error in logs (for filters) - and that other error gave me a hint where is a problem.

Duplicate #953236.
Appears with no ctools installed.
Appears with no filters exported.
