Originally I had a file external which pointed to the same repository but under a different server name. (i.e., under a CNAME rather than under the name I used during checkout.) I then checkout'd (rather: svn up --set-depth'd) with 1.5, which complained about the external being a file external. So I 'svn upgrade'd and ran 'up --set-depth' again. It died with an assertion.
