After a whole evening running tests and no failures (and thus no way to test the fix), the new ppa gave this result after less then 10 reboots:
Sep 2 00:21:06 laptop console-kit-daemon[1111]: WARNING: tried but failed Sep 2 00:21:06 laptop console-kit-daemon[1111]: WARNING: eventually choose to use 12 Sep 2 00:21:06 laptop console-kit-daemon[1111]: WARNING: first fd was 3 Sep 2 00:21:06 laptop console-kit-daemon[1111]: WARNING: retried 1 times
So the workaround/test works for me.
