Thanks for report! This error is reproducible on other machines. I am 
analyzing the cause.

Failing test case (on nvm workspace):

mtn log --from 045b0286268ed071e6ac83bc87cdcb751b38718f

fails also here, but in somewhat different place (maybe it's a buffering 
problem?):

And for the rest - here is the backtrace:
