I tried to add a PDF to an already-released homework assignment. I went to "Manage Assessment Attachements" --> Add hw1 Attachment --> attached the PDF, then I got a 500 error with the following error message and stack trace:

This was a CMU-specific issue. I created the directory and we should be fine.
