When I try to change the settings for a field collection field with tabs I get the following error.

Attempt to update field Tabs failed: Cannot add index field_tabs_revision_id to table field_data_field_tabs: index already exists..

It even happens when I only try to change the help text. I'm not sure it's a Field Collection or a Field collection Tab formatter issue.

Some test results:

  • On a fresh Drupal install this module works fine.
  • When I deleted all nodes where the filed with tabs had content, updating the field settings succeeded. When I add some content again to a node's tab field, updating the field settings also succeeds.

Might this be related to the update of the Field collection module in March? Content added before that date gives problems?

Perhaps someone can give me some advice where to look.
