Another High Sierra crash?

    Here's another case my user-with-crash-problems sent me - my app is opening a window, and he's one of two people reporting problems.

    The window does crash some pictures in its Listbox.Paint event, but otherwise it's nothing fancy.

    The app is built in Xojo 2016r3, so it uses old-style graphics, not the modern ImageSets. Should I be looking at the multiple-of-fours issue?

    Here's the crash log, someday I'll know enough to be able to figure these things out for myself, but in the meantime can anyone take a quick look and tell me what it looks like is causing the crash?

    Any help would be greatly appreciated, thanks!
