@fretzl : wich version of JUZ have worked with your 1.2.7 ? I only tested with 1.2.8 and nightly build. Also I think your 1.2.8[5056] is the nightly build so give it another try with JUZ trunk version, and check if "version" is set to 129 in option XML file and if it crash again can you post here the last log. Thank you.
