Radioactivity + Link Field Module

Hello,

Our site is running both the Link and Radioactivity modules.
We use the Link module to add "Related Links" to nodes ("segments" content type) on our site, and have found that these often disappear after addition.

Inspecting the log, we discovered an error message relating to Radioactivity checks:

Location: radioactivity_ajax.php
Details:
PDOException: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ')' at line 1: INSERT INTO {field_data_field_rel_links} (entity_type, entity_id, revision_id, bundle, delta, language, field_rel_links_url, field_rel_links_title, field_rel_links_attributes) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2, :db_insert_placeholder_3, :db_insert_placeholder_4, :db_insert_placeholder_5, :db_insert_placeholder_6, :db_insert_placeholder_7, ); Array ( [:db_insert_placeholder_0] => node [:db_insert_placeholder_1] => 6357 [:db_insert_placeholder_2] => 55781 [:db_insert_placeholder_3] => segments [:db_insert_placeholder_4] => 0 [:db_insert_placeholder_5] => und [:db_insert_placeholder_6] => book/recipes/potatoes [:db_insert_placeholder_7] => L'Etoile's Tips For Great Mashed Potatoes ) in field_sql_storage_field_storage_write() (line 424 of /mnt/www/html/wpr/docroot/modules/field/modules/field_sql_storage/field_sql_storage.module).

It appears that Link is throwing a MySQL error when Radioactivity examines nodes with link fields.
