Invalid Repository Name

[supertylerc]

Using PR #1, I built the plugin as follows:

go get -d ./... && go build

I then copied the resulting binaries to the bin directory in my path, alongside packer.

I don't have issues with any other post-processors (so far). I've successfully used the docker-tag post-processor. Removing it from my Packer template does not change anything: the failure occurs in the same way. I've also tried using export_path instead of commit, but this resulted in a different error.
