The problem was specifically that just having xdg-open installed doesn't
guarantee that the user has configured it.
The code currently approximate "is it configured" by checking the
desktop environment in use.  It's clearly a gross hack (or a crude
approximation), so if you know a better way, we'd like to hear it.
