What you've found is the least sucky way to work around this right now, but see my https://public-inbox.org/git/87inc89j38....@evledraar.gmail.com/ and https://public-inbox.org/git/87d0vmck55....@evledraar.gmail.com/ for some prior (and recent) discussion of this problem on-list. FWIW this has nothing to do with git-svn per-se, and also e.g. happens to me when I do a 'git fetch --all' sometimes on git.git.
