Hi Albrecht,

I am sorry that I cannot check it right now, but it may be that
ConfigurationOfOSProcess needs to be updated. The #ifNotNilDo: problem
was fixed by Thierry Goubier in July 2017, so perhaps you are using
an out of date version.

Hopefully someone else can give you a better answer, otherwise I will
try to follow up in a day or two.
