stree command no longer opens the project

Since upgrading to SourceTree 3.0, the 'stree' command no longer opens the project of the current directory. I've also tried 'stree .', but still all that opens is the SourceTree window with the Drag and Drop a repository. I've tried reinstalling the command line tools and also logging out and back in, but the behavior is consistently broken.

stree --version reports version 1.3

Also, it seems that Open Recent also fails to open the projects, so the issue may not be related to stree but to a bug in SourceTree opening projects.

I am able to open a project with Cmd+O and navigating in that dialog.
