   4 `feature/multikernel` has patched python-dbus bindings that fix this
   5 bug (tested on various 32-bit single core and 64-bit multi-core
   6 hardware and VM).

  13 Logs for various crashes experienced when cloning, on amd64 kernel,
  14 follow. At least one similar bug was triggered on 686-pae kernel
  15 (64bit CPU) too. Launching the program with various linux32's options
  16 does not help.
  17
  18 Other kinds of crashes were seen on a Wheezy amd64 kernel + amd64 userspace.
