Redmine

When I runing:

/usr/share/redmine-1.2.0/extra/svn/reposman.rb --redmine https://example.com --key=mykey --svn-dir /var/svn --owner www-data --url http://example.com/svn-private/ --verbose

Unable to connect to https://example.com/sys/: wrong constant name Feature-twitter-oauth

The most projects uses svn, but I have one project with git. And "Feature-twitter-oauth" - the name of one branch in this repository.
When I disable project with git - reposman.rb works correct again.
