SQL Compare "2 conflicts prevent checkout"

When attempting to generate scripts using SQL Compare it hangs for a few minutes at "Generating SQL" then bombs with the error "2 conflicts prevent checkout."

 The first obvious issue is that SQL Compare is not reporting which things are in conflict, so I cannot resolve the issue.

The next is that the exception message is being thrown from LibGit2Sharp. We are not using the git backend. We're using Team Foundation Version Control.

Below is the exception message. I tried to use code tags, but they don't seem to work on this site. I'm seeing a pattern emerge...
