I'm running the iTerm2 beta (v3.3.10beta2) and I've configured SourceTree to use it as its terminal. When I click the "Terminal" toolbar button in a repo's window, iTerm activates and moves to the foreground, but doesn't navigate to the repo's directory. When I click back to SourceTree, it's logged an error:

There was a problem opening this repository in iTerm2.
An error occurred while trying to open iTerm2 with this repository. Please file a support ticket via the Help menu.

I did some quick grepping through the Console app to see if I could find any germane messages, but nothing jumped out at me. Happy to do a little more digging if you folks can point me in the right direction though.
