6600 A possibly relevant merge request was started @ https://invent.kde.org/plasma/libplasma/-/merge_requests/1053 oddly enough i can reproduce a crash while dropping the addressbar url, *but* not with this backtrace, but a slightly different one with an assert, which the above merge request fixes Git commit 7ec09e5fb794d3280a03774c8499ddc92b3b3322 by Marco Martin. Committed on 09/02/2024 at 13:14. Pushed by mart into branch 'master'. Guard against invalid URL mimedata with no urls It's possible that the dropped mimedata claims to have urls, but its actual url list is empty. This happens for instance when droppping the url of chromium from its addressbar.

Created attachment 165206 [details] long backtrace STEPS TO REPRODUCE 1. run Vivaldi browser natively on Wayland - I did not test with another browser 2. load any website 3. drag the loaded url and drop it on desktop - a context menu opens 4. choose the option from the context menu used to create a Sticky Note Operating System: KDE neon Unstable Edition KDE Plasma Version: 6.0.80 KDE Frameworks Version: 5.249.0 Qt Version: 6.6.1 Graphics Platform: Wayland
