Issue after upgrading to Drupal 7.16

This happens in field_tokens() which has nothing todo with Display Suite afaics, so I'll leave it open for now. You'll need to give me some more steps to reproduce the error.

I also encountered this problem.

It only happens when trying to use display suite to modify the layout for user profile (admin/config/people/accounts/display).

I am not sure if it is specifically related to drupal 7.16. I only tried to modify the layout with DS until a couple of days ago, and I already had drupal 7.16 by then.

Please let me know what kind of info would help. I checked the watchdog but couldn't find any useful info.

I was getting the same error. I had a vie on the user profile view panels template. That rendered a view content pane that hat a field of a rendered user using ds as a custom display mode.

cc did not solve the issue. But disabling all fields and re-enabling them solved it for me. Does it solve your problem as well?

Well Profile2 has no real support for now, see #1833320: Profile2 support (display and forms) - I hope to get a project soon that we need this so I can built this into DS.

I am not using Profile2...

Cross-referencing, same (?) issue with the new 2.2 release:
#1928514: Fatal error on User page

I realized that my workaround did not solve the issue.

Still can't reproduce this. I'm on latest core and have configured a lot of stuff. So closing until I get clear steps to reproduce.

Changing description

Note: This error is usually related when passing empty or invalid entity argument into token_replace() or similar function.
