When I click the "Configure your wagn" link on the default homepage after creating the default admin user, I receive the following error:

Rendering /apps/wagn/public/500.html (500 Internal Server Error)

consistently when I try to lauch v1.4.  I was previously running v1.0 without error.  I've tried an upgrade as well as a clean install, both from the package on rubyforge as well as from the .git repository.  I've followd all of the tips on the installation page to no avail.  Am I missing something?
