--- Comment #10 from Jürgen Reuter <juergen.reuter at desy dot de> --- After I completely recompiled the trunk version (r199585) the problem is gone. So most probably it resulted from an incomplete update and recompilation of the code, or was in an intermediate step of the development, which seems to be gone by now.
