I created branch, committed and pushed, created a pull request against a branch and then committed an additional change to that branch.
GitVersion parses the original commit (2.0.1-abc.1+1), the first PR (2.0.1-PullRequest.5+2) and the second commit (2.0.1-abc.1+2) but throws the above exception when parsing the PR. There are 3 tags against the repo.
