The darktable magicians have crafted something again - detail mask

But … there appears to be a problem … there is some sort of conflict when exporting images to a jpg either on disk or email.
I am running the daily git/Manjaro/Arch/XFCE
First indications were that my system locked-up and/or crashed


This is the typical problem but on one occasion the lower part of the image was filled with stripes.
All works really well … tested with several modules … just the export situation.
