Hi, now that my bug is almost 1 year old, i checked its status again. It's still present. I've looked at Atsuhito Kohda's report and found that i have a symlink linking /usr/share/texmf/web2c/ to /var/lib/texmf/web2c/. So this doesn't seem to be a solution. Still hoping the bug won't turn 1. Good luck Sander
