Course deletion doesn't seem to be ironed out yet, at
least if there are people assigned to the course. The
Admin Site "Remove a Course" reports success and the
removed course doesn't show up any more on the Admin
Courses screen. However, it still shows up on the
students' and instructors' "My Course" lists. Even
after the admin removes people from the course, it
still shows up on their "My Courses" list, although it
no longer appears on the "Drop Course" list. If
instead, the user tries to drop the ghostly course
themselves, they'll end up at a URL like:
/coursework/servlet/RegisterCourse?key=173639101
with the error, "There was a problem adding you to the
course."

Have you tried refreshing the course lists in Site Admin ?
This rewrites the templates that are used for displaying
certain areas of a users view onto the system. For instance,
the list of available departments is generated into a static
DTL page that is personalised for the user. I havent tested
the senario in the bug, but the comment about ghostly
courses sounds like a stale DTL rather than a problem with
the database.
