--- Comment #3 from Antti Savolainen <antti.s...@gmail.com> ---
Oh, this is exiting finding a working crash in old reports

I followed your instructions and and kinda panicked when after left and right
clicking layers started disappearing. I Ctrl+z a couple of times to reverse the
changes, which came out not as it was supposed to and eventually a crash.

Build & Platform:

    krita 4.1.0-pre-alpha (git hash: 4a3af9a)
    Xubuntu 17.10

Video demonstrating the crash: https://www.youtube.com/watch?v=Yn1TIg22ro0
