git svn init throws Not a git repository (or any of the parent directories): .git

Hi all,

I have problem with git svn init:
When I execute
git svn init svn+ssh://username@example.com/path/repo
I see:
fatal: Not a git repository (or any of the parent directories): .git
Already at toplevel, but .git not found
 at /usr/lib/git-core/git-svn line 342

But when I execute: git svn clone svn+ssh://username@example.com/path/repo Everythins is ok and I see: Initialized empty Git repository in /tmp/svn_migration/repo/.git/

Any hints why it's no working? I prefer to do first init and then fetch, because I can fetch selected revisions (git svn fetch --revision 1:1000) - so it's easier for me to split migration into groups lets say 1000 revision at once.

My software versions: git version 1.8.1.1

svn, version 1.6.12 (r955767)
   compiled Feb 17 2012, 10:36:45

Best regards.
