What you've found is the least sucky way to work around this right now,
but see my
https://public-inbox.org/git/87inc89j38.fsf@evledraar.gmail.com/ and
https://public-inbox.org/git/87d0vmck55.fsf@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.
