git-svn `Repository has moved' error

We recently had a new subversion server replace an aging one, taking over the same hostname / ip and adding in a sourceforge-like system. Since then, I can't use git-svn to commit to the repo. I get this error message when trying to dcommit:

  Committing to https://code.sci.utah.edu/svn/Tuvok ...
  Repository has been moved: Repository moved temporarily to
  '/gf/project/?feedback=Page Not Found. Try searching for projects';

I've tried a fresh clone, and upgrading to 1.6.2.4 manually, with the same results in both cases. My subversion bindings are from version svn 1.6.1.

I can update/commit from an svn-managed checkout without issue. I've tried a working copy I had lying around since before the move.

Any ideas / workarounds?
