Fwiw, I followed the exact same steps and have the same result as
Martin. I'm not able to reproduce the issue either.

Paul, this looks like something specific to your system configuration, a
default jessie system doesn't seem to be affected.

You mentioned you have tools like cgrulesengd etc running. Maybe they
are interfering.

Would be great if you can reduce your problem to a minimal test-case
based on a default jessie installation.


Thanks,
Michael
