Notice: Undefined index: taxonomy_term in taxonomy_field_formatter_view()
Saw this error today Drupal 7.0:
* Notice: Undefined index: taxonomy_term in taxonomy_field_formatter_view() (line 1368 of ./modules/taxonomy/taxonomy.module).
This fixed it - http://drupal.org/node/934726#comment-3924552
Supposedly this is fixed in Drupal 7 HEAD
