Comment 1 Aleix Pol 2023-02-08 01:21:37 UTC

Could it be an installation issue? Can you check if you get any error messages when running Spectacle on the terminal?

It does seem to be calling a null pointer but I don't see why we'd get one if it's all properly set up.

Comment 3 Bug Janitor Service 2023-02-16 16:18:07 UTC

A possibly relevant merge request was started @ https://invent.kde.org/graphics/spectacle/-/merge_requests/202

Comment 4 Aleix Pol 2023-02-16 16:20:10 UTC

My MR above will address the crash, but is it possible that your desktop file is broken? It should have the X-KDE-Wayland-Interfaces in question. Can you investigate a bit what could be going on?

Comment 5 Patrick Silva 2023-02-16 17:29:40 UTC

You are right. I can't reproduce the crash with another user account.
The .desktop file of the working account is located on /usr/share/applications,

The broken .desktop file is not removed after uninstalling Spectacle.

The problematic user account has a shortcut to Spectacle on desktop, could this be related?
