      When using KDevelop on a Plasma/Wayland session I'm constantly experiencing crashes when doing code completion. The crash is triggered in QtWayland.

      Application: KDevelop (kdevelop), signal: Aborted
      Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

      If needed I can run kdevelop through WAYLAND_DEBUG env variable as it's fairly simple to reproduce
