Comment 0 for bug 1564976

I was doing some testing and found that if I create /etc/udev/rules.d/70-test.rules with:
KERNEL=="kmsg", TAG+="test.some-test-name.1"
KERNEL=="kmsg", TAG+="test.some-test-name.2"
...
KERNEL=="kmsg", TAG+="test.some-test-name.10000"

Then run: 'sudo udevadm trigger', I could reliably trigger this crash.
