The table old_issues has a primary key defined on the issue_id column.
This issue_id comes from the issues table when an item is checked in.

In some case the value of issue_id already exists in the table

Basically this happens when an item is returned and mysqld is restarted: The
auto increment value for issues.issue_id will be reset to MAX(issue_id)+1
(which is the value of the last entry of old_issues). See also the description
of bug 18003 for more informations.
