      Description

      Steps to reprodce:

      1. Install a Moodle 2.x, for some x that allows you to create an old mod_assignment.
      2. Create a test course with an old-style assignment in it.
      3. Upgrade to Moodle 2.8 or later.
      4. Note that the assignment is not shown on the course page.
      5. Note that in the grade report, the column for the Assignemtn is shown, with no link in the column heading.
      6. Click the Single view icon for any row or column.

      Expect result: Something sensible is displayed.

      Acutal result:

      I expect this happens in any case where you create a graded activity, and then un-install the plugin. (So, most likely with a plugin installed from the plugins DB.)
