Routine dependencies confused by <insert ... on duplicate update>

Which version of common_schema are you using? (specify
revision+distribution)
2.2.11
revision 523

Which component is failing? (specify the view, function, etc.)
get_routine_dependencies

What is the expected output? What do you see instead?
An insert statement with <on duplicate key update>
will make the get_routine_dependencies procedure think
there is an update to a table with the 
name given by the column name.
The procedure should not report col2 below since this is a column.

+-------------+-------------+-------------+--------+
| schema_name | object_name | object_type | action |
+-------------+-------------+-------------+--------+
| myschema    | col2        | table       | update |
| myschema    | mytable     | table       | insert |
+-------------+-------------+-------------+--------+

Can you provide with sample data?
create procedure testproc(
  var1 int,
  var2 int
)
begin
  insert into mytable (col1, col2)
  values (var1, var2)
  on duplicate key update
    col2 = var2;
end

(As of version 1.1), please provide output of
SELECT * FROM common_schema.status
