Non-malicious traceback in OpenSesame 3.1.3 on Mac

[dschreij]

When working with OpenSesame 3.1.3, I see the following traceback in my console, but don't notice any problems in OpenSesame itself at all.

Traceback (most recent call last):
  File "/Users/daniel/Github/OpenSesame/libqtopensesame/widgets/tree_overview.py", line 314, in mousePressEvent
