"Destroy track" not working

[kingqueen3065]

On clicking "destroy track" on a user's admin page,

Alaveteli returns a blank webpage and doesn't delete the track.

I think, in this case, the track had already been deleted. Error message:

A NoMethodError occurred in admin_track#destroy:

  undefined method `destroy' for nil:NilClass
  app/controllers/admin_track_controller.rb:24:in `destroy'

It was still showing as in place on the user's admin page - I tried refreshing it a few times after I returned to it when I got the blank page, and it was still there, with the "destroy" button.

That TrackThing definitely doesn't exist in the database, so closing this until it comes up again.
