Comment 5 for bug 1527309

This thread hints at the cause of the problem, and a possible solution: https://forums.wxwidgets.org/viewtopic.php?t=16887

However, the solution doesn't quite work - it solves the segfault,but changes the behavior.

Ideally, since I'm working on cleaning up the preferences anyway, I'd like to ditch this approach entirely and make the listview directly editable. Thoughts or objections?
