[LON-CAPA-admin] course is empty

Fri Jul 30 14:26:57 EDT 2010

Actually, that's not a 2.9-specific error.

We thought it was fixed (or at least caught), but apparently not. It is a corrupted cached course environment on that server. I guess we should just throw away those environments when we are done with them.
