After upgrading from Git plugin 2.0.1 to 2.0.4 all existing builds on our installation fail. Downgrading is the only way to restore system function.

The configured branch for each job is correct and does exist locally on the build nodes.

An example of a failed build is as follows:

Started by remote host 127.0.0.1 with note: Triggered by commit
