In Thunar-4.15.0 (on gentoo), SEGV occurs under the following conditions. * last-side-pane is "void", thunar startup always failed in SEGV. * after startup, hide sidepane and toggle "Show Hidden Files" caused SEGV. I tried "git bisect" and found caused commit 2f97d3e6f9bfde0d911d569ca5ea125f64a2c2d5. And I made a patch to fix this problem.
