The problem here isn't with git-svn; rather, it is with the svn
repository at oss.oracle.com claiming a nonsensical UUID.  svn uses
UUIDs behind the scenes to identify each repository, and git-svn does
the same thing.  When doing git svn init (or clone, which is just init
&& fetch) the svn server sends back a UUID which identifies it.  When
I use wireshark and expand the first HTTP packet back from a good svn
server, I see something like the following embedded in the xml tree:

<lp3:repository-uuid>
612f8ebc-c883-4be0-9ee0-a4e9ef946e3a
</lp3:repository-uuid>

However when I do the same with oss.oracle.com I see

<lp2:repository-uuid>
????????-????-????-????-????????????
</lp2:repository-uuid>

git-svn tries to play along for a while, but the bottom line is that a
string of question marks isn't a UUID.

There's more about svn's use of UUIDs in the svn book.  Perhaps the
admin of oss.oracle.com can correct this UUID problem so one can use
git-svn with this repository.
