Nesting level too deep - recursive dependency?

I have a Drupal Commons 2.6 install, and have used Features override to save the overrides before I update Commons.
When I followed instructions, selecting all overrides I got this error message:

Fatal error: Nesting level too deep - recursive dependency? in /home/otakinet/public_html/commons/profiles/drupal_commons/modules/contrib/ctools/includes/export.inc on line 664

I discovered that the override that has the problem is

CTools export API
features_override:features_override:1
Features override
tto_user_dir_jun12
Dependencies
commons_profile ctools features_override

When I did not select this one feature overrride, the other (8 overrides) exported as expected.
When the above override was included the process failed.

When I tried to export that one override alone, it also failed.

I went back and deleted that override and recreated it: it will not export, same error message.
This lists in the overrides drop down as Views user_directory
