            Description

            I am using Moodle 2.1.1 on RH6 with mysql.

            Whenever the default grade letters for a course are changed and I duplicate any course content I get "Error writing to database".

            In the log it shows:

            Duplicate entry '209685-0.00000-F' for key 'mdl_gradlett_conlowlet_uix'
            		 
            INSERT INTO mdl_grade_letters (lowerboundary,letter,contextid) VALUES(?,?,?)
            		 
            [array (
            		 
              0 => '0.00000',
            		 
              1 => 'F',
            		 
              2 => '209685',
            		 
            )]

            What can I do to correct this problem?. Is there a patch available ?

            Thanks, Jose
