Could it be some kind of a race? When originally tried with my complete
config I had different results with and without (require 'easy-mmode)
before killing scratch buffer. Probably you can try with this line as well?
Also I noticed that if you press q in this case emacs just kills this
opened buffer. So probably emacs is in some mode in this case - can I check
it somehow?
