unable to resume git svn fetch

Hello,

I am trying to import a SVN repo that I will be tracking for the foreseeable future.
The clone command was
git svn clone -T trunk -t tags -t release_tags -b branches -b private/branches $REPO

The fetch has been interrupted several times. Up until now I have had no problem resuming with git svn fetch.

Now, fetch fails on r9007 with 
	Incomplete data: Delta source ended unexpectedly at /opt/local/libexec/git-core/git-svn line 5117

I see some messages on the BUG mailing list regarding this error, but I get somewhat lost in the details of the repair and trying to understand how I might apply them to my scenario. Also, 

git svn log
and
git svn reset -r9006
fail with
	fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree.

More detail from my shell session is at https://gist.github.com/79e08fe7551875f8bce9

This is git v1.7.3.3 on OSX v1.6.5 via MacPorts. I see that 1.7.3.4 is out, though not in MacPorts yet and nothing in the 
release notes lead me to believe it would be useful, though I am certainly willing to do a source install if it is.

It was suggested in #git that I ought to limit the amount of history I am importing. I think that's a cop-out, but I'll listen to a reasoned argument why that opinion is wrong.

Thanks in advance,

Justin
