A possibly relevant merge request was started @ https://invent.kde.org/plasma/kwayland-server/-/merge_requests/25 Git commit 5167c11b7dfe0520ef34ca0d237c480101eec17f by David Edmundson. Committed on 22/06/2020 at 23:23. Pushed by davidedmundson into branch 'Plasma/5.19'. Scope dragAndDropActionsChanged to source lifespan The source can have a different lifespan to the offer being made. If a source is removed and we get a drag actions changed before the offer is cancelled we don't want to crash. Couldn't reproduce locally, but the trace was good.
