Unfortunately, I still cannot reproduce the issue myself. It works perfectly in my VM. However, all cores, I've seen so far were related to a call to function unit_unwatch_pid in manager.c. I have now built some testpackages with a proposed fix for this call. Please find them at: bsc918226/standard/">http://download.opensuse.org/repositories/home:/tsaupe:/branches:/openSUSE:/13.1:/Update:/bsc918226/standard/ Would be good if you could quickly test them and report freedback.
