Export folder change results in crash

I have identified the following problem:

A regularly (but not always) reproducible immediate crash of Cubase 8.5 – when in the audio export dialogue I simply try to change the path of the export folder. Upon click in around 30% of the cases, Cubase simply quits.

Anyone?

Cubase 8.5.15, Apple Macpro 2008, OS 10.11.4
