What should have happened?

No crash.

Replicated/Tested on

0.92.x build (custom build, up to date with gitlab), Linux Mint 19.1
0.92.2 5c3e80d, 2017-08-06, OS X 10.11.6 (15G20015) "El Capitan"
0.92.3 (2405546, 2018-03-11) ppa, Linux Mint 19.1
0.92.4 latest flatpak, Linux Mint 19.1

Caveat: failed replication

Not replicated in latest brew (compiled) (0.92.3 2405546, 2018-03-11) not viable alternative as too buggy
Not replicated in 1.0alpha up to date with master, Linux Mint 19.1
Not replicated in 1.0alpha (9dee831, 2019-01-15), AppImage, Linux Mint 19.1

Edit: note I ended up replicating in 1.0alpha by flipping the y axis
