Error 128 when trying to migrate SVN branches with white spaces in the name

[Marcelo Filho]

I'm trying migrate a SVN repository to Git. But the 128 error is showing up when the JAR is trying to migrate a SVN branch with white spaces in the name, for example:

fatal: Not a valid object name refs/remotes/Branch With White Spaces
cat-file commit refs/remotes/Branch With White Spaces: command returned error: 128

Below is the command that I'm executing to do that:

git svn clone --stdlayout --authors-file=authors.txt https://svn.repodomain.com/my/svn/repo

Thanks.

The rev-parse command is the culprit in my case;
