taking default action for signal 11 Segmentation fault (core dumped) Apitrace of the run is attached. This doesn't happen with the proprietary driver, and I can't confirm it's a regression, but there appear to be reports of VMD working on nouveau (albeit slowly).

Update: happens only on Wayland, and I remember seeing a similar issue on radeonsi.
