GNOME screencast crashes when stopping the recording, with stack trace:

gjs[7730]: JS ERROR: TypeError: this._pipeline is undefined
    stopRecording@resource:///org/gnome/Shell/Screencast/js/screencastService.js:185:9
    StopScreencastAsync@resource:///org/gnome/Shell/Screencast/js/screencastService.js:472:18
    _handleMethodCall@resource:///org/gnome/gjs/modules/core/overrides/Gio.js:354:35

    start@resource:///org/gnome/gjs/modules/script/package.js:190:8
    @/usr/share/gnome-shell/org.gnome.Shell.Screencast:1:17

It looks similar to this issue but it seems I have the required libraries installed: xdg-user-dirs-gtk, gstreamer1.0-plugins-*...

Any idea ?

System info:

  • Ubuntu 22.04, Linux 5.17.0
  • Nvidia proprietary driver 520
  • gnome-shell 42.5-0ubuntu1
  • pipewire 0.3.48-1ubuntu2

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
