Same error here with a Creality K1 but along Y axis and no error along X axis (thanks for the hint by the way it helped me today as it appears the bug is only along one of the plane axis).

[sergakaibis]

Same error with version 1.9.1, MacOS, with any printer and Y-axis mirror is broken also.
ADD: error occurs only after usage of "Auto-orient", manual "Lay on face" seems to be ok

[exzhawk]

Same erro with version 2.0.0-rc, Windows. Creality K1C.
reproduce step

1. new project
2. import model
3. lay on face (select the front face)
4. right click - clone 1
5. right click the cloned one - mirror along y axis
6. shift+a to arrange
7. slice plate

[lennoxdk]

same error mirror and rotate

[BETLOG]

+1
lay on face (affects a 270 degree Y axis rotation)
right click, clone, +1
move clone a few mm away from original in ~X axis
mirror (clone), X axis
dolly/pan/zoom view, deselect clone, or leave it selected... seems to make no diff
slice (tab - which is extremely unreliable in linux BTW, pressing tab to slice may or may not happen ~50% of the time)
app exits silently
