Comment # 1 on bug 1126163 from Ulrich Windl

Checking the bugs at https://developer.blender.org this seems to be a problem
that might have been fixed upstream recently. Also I could reproduce the
problem with a different build:
# Blender 2.79 (sub 0), Commit date: 2017-09-11 10:43, Hash 5bd8ac9abfa
