-- Information about the crash:
- What I was doing when the application crashed:

Launched the application, selected the "40 hour template", "use this template",  clicked "+New", "basic project", "use this template", then "+New".

Application crashes every time for me when performing the steps above.

Running F20, mate window manager.

The crash can be reproduced every time.
