git-svn problems with branches containing spaces

Hello,

As I have reported yesterday on IRC, git-svn has problems with branches
containing spaces.
I get the following message, when I want to clone from the repository
containing a branch with a space.
Cloning until the revision the branch is created everything works fine.

fatal: refs/remotes/Modbus Error Limit Fix: cannot lock the ref
update-ref -m r1897 refs/remotes/Modbus Error Limit Fix
ff0819c8e9c97c24e9865bc868c503fd9b64f980: command returned error: 128

Thanks for your help.

Best regards

Robert Ewald
