I have the dashboard running on my recent runs on obelix

For one of the runs I moved the submit directory

I then get an Internal Server Error as the dasboard cannot access the workflow specific database.

http://obelix.isi.edu:8000/root/5/workflow?wf_uuid=ccf5ae78-bc80-497d-a6ee-4d7ac1210ae1

Instead of throwing an internal server error we should have an error page that says that the directory / db URL not accessible

Here is the log from the dashboard tool.
