Ok, still having the problem.  I switched to a completely new clone of galaxy, and even started on a completely clean installation of Postgres for the backend.  No matter what I do, i get the same error when trying to transfer data from file system paths.  Managing a data library by adding data via file upload works fine, but is not useful for large files of course.  

I can't find any issues in the code, and have tried various file types as well.  I'm at a stand still with galaxy right now, and am simply working on figuring out this problem until its resolved.  Thanks for any other ideas you might have.
