Segmentation fault at wl_map_insert_at
Wayland version: 1.18.0 (Arch Linux packages)
I'm testing the Plasma 5.21 Beta with KWinFT, so the compositor may be misbehaving. But since there seems to be an illegal state within wayland-client, I thought it may be interesting to share the debugging information with you.
plasma-browser-integration-host crashed after I closed a Chromium window, with this backtrace:
