Crash with "TypeError: Cannot call method 'serve' of null"

[HontoNoRoger]

My Yeti server has been started with yeti --server --loglevel info and crashed after some tests were run. Unfortunately I can't really reproduce it, therefore I don't know what's causing it.
Maybe the output will help you:

If you believe this is a bug in Yeti, please report it.
