Comment 1 David Edmundson 2020-01-14 19:26:55 UTC
Cannot reproduce. 

Please can you confirm which wallpaper type you have active. It'll make a differnce as the crash is an evaluation happening on close with one widget in that view.

Active wallpaper types
Comment 3 Patrick Silva 2020-01-14 20:23:06 UTC
crash always reproducible on Arch Linux when I switch from folder view to Desktop and vice-versa.

Also reproducible on Neon unstable edition if System Load Viewer widget is present on desktop.

Comment 6 Nate Graham 2020-01-22 20:54:39 UTC
Hmm, this has stopped happening to me.
Comment 7 Patrick Silva 2020-01-22 21:13:05 UTC
still reproducible on Arch + Plasma 5.18 beta :(
Comment 8 Patrick Silva 2020-02-11 16:19:12 UTC
crash is still reproducible on X11 if System Load Viewer widget is present on desktop.
On Wayland Plasma crashes even without System Load Viewer widget on desktop.
