"SuspiciousOperation" Error While Deleting an Uploaded File

[Ty]

When I login to the administration and try to delete a file I get a
"SuspiciousOperation" error. Here's the traceback:

Here's my full model:

Any help would be appreciated.

Apache permissions must be set on the directory. I was having the same
issue before I set the directory group to be Apache and gave it RWX
privileges

That's the thing... (and I probably should have mentioned this) I'm
developing on Windows XP using the "manage.py runserver" command to
serve the files.

Turns out the problem was the FileField value. It can't start with a
forward slash, it has to be relative.
