Notice: Undefined index: uuid_term in uuid_features_features_pipe_taxonomy_alter() (line 69

Same error shows up whenever I visit the 'recreate' page for a feature.

I too have seen this, looking into it.

This only happens when your vocabulary has no terms (yet). You have three options:
1) ignore the error
2) create at least one term in vocabularies referenced by the feature
2) patch uuid_features.module. Add this line before the line 69:

+  if (!empty($export['features']['uuid_term']))  // fix
      $pipe['uuid_term'] = $export['features']['uuid_term'];

Patchified #3 (change is line 100 of uuid_features.module as of this comment) - works for me, and applies cleanly to -dev.

Awesome, thanks @geerlingguy!
