I have now commited a patch to git that might fix your issue. Please
test:

http://cgit.freedesktop.org/systemd/systemd/commit/?id=75c8e3cffd7da8eede614cf61384957af2c82a29

I assume this fixes your problem, but since our kernels actually have
audit enabled I am a bit too lazy trying to reproduce the issue here, so
I'd be very thankful if you could test this!
