What version are you running?
RBTools 0.7.9

Python 2.7.12
What steps will reproduce the problem?

"rbt setup-repo" in git-svn root directory
enter repo url


What is the expected output? What do you see instead?
Should initialize git-svn repo, but shows python error instead.

After "fixing" the error by removing the offending keyword, git-svn only offers the git repos on the rb server, instead of the svn repo.

What operating system are you using?
Cygwin on Windows 10

Attach the debug out from the command.

$ rbt setup-repo -d
