mac: Design Studio occasionally crashes just after creating a new project

Using the latest snapshot, build number 338, Design Studio occasionally crashes just after creating a new project / opening an existing project.

Steps to test:

1. Open the Design Studio
2. In the Welcome screen, click "Create New" 
3. Create a project with the default settings and click "Finish"
4. -> Design Studio may crash

When testing this, crash did not happen every time, but several times altogether.
