I've updated to the latest head on my feature branch FB-001. I right-click default's head and choose "Diff to local", then I receive the above stacktrace.

"file/that/not/longer/exists/in/branch" is a file that was renamed, hence it no longer exists in the head of FB-001. It's also never made it into the default branch.

If I do things the other way round (update to head of default, "Diff to local" on FB-001 head), I get the diff as expected.

    Today I tried to repro this and couldn't. Same repo, didn't run verify, etc. So I'm going to chalk it up to a random cosmic occurrence. :) You can close the bug, if it happens again I'll add more info.
