sbt/sbt-git-plugin — Issue #10: doesn't work with global install

when I put the plugin in my ~/.sbt/plugins/plugins.sbt file and I put useJGit in ~/.sbt/user.sbt
I get the following error:

[error] AttributeKey ID collisions detected for: 'git-runner' (sbt.Task[com.jsuereth.git.GitRunner], sbt.Task[com.jsuereth.git.GitRunner], sbt.Task[com.jsuereth.git.GitRunner])

It is being used in a project that has many references to other projects on the filesystem, I have no idea what that error means or how I should start resolving it.
