A friend found a workaround to reduce/remove the stripes in the images:
Increase the imagecache size. This reduces the amount of artifacts. In
his case to "none". this is usable for those blends where RAM is
sufficent to hold everything (but not the default 1Gb).

This is a hint that the problem lies in the imagecache code.

Status in Hugin - Panorama Tools GUI:

Bug description:

And it creates a lot of artifacts on huge panoramas.

I had to create screenshots since gimp didn't allow me to save the image (not enough ram). 
Here's the file hugin created: http://downloads.moeeeep.com/panoramabug/pano5.png (402mb --> needs at least 6.6gb ram to display).  It has a size of  61638x10876 pixels
