I got the following notice on a site where I enabled a feature after using the Minimal installation profile.

Notice: Undefined index: fields in field_info_field_by_ids() (line 664 of /[path]/modules/field/field.info.inc).

As the site has no content types, nor fields yet my "guess" is that this module actually does not check if it is so and just tries to output that tab anyways.

It should check if the indexes exists and skip those who doesn't
