Sorry about that. Commit 82f699a676f59001dafe0eb808fe46c0955fde79 should work.

test/stress.py causes systemd --user to stop responding to dbus (at least for me)

Sorry for the late response on this. Your test program needs gcc 4.9 to build, and I had to switch over for rawhide for this first.

However, I cannot reproduce the bug. I've ran your test suite excessively, in a loop, with other stress tests in parallel, but I don't see any issue.

Possibly, some recent changes to domain accounting fixed the crashes you saw. Could you test this again with the current kdbus git head please?

It works for me too. Thanks.
