--- Comment #8 from javama...@gmail.com --- I seem to have this issue intermittently. Discover will work fine for weeks/months, then it will start crashing every time I try to open it. It will fix itself after a week or two. Here's the terminal run: kde-swiebel@T5600-kde:~$ plasma-discover Invalid Context= "Legacy" line for icon theme: "/usr/share/icons/Adwaita/8x8/legacy/" Invalid Context= "Legacy" line for icon theme: "/usr/share/icons/Adwaita/16x16/legacy/" Invalid Context= "Legacy" line for icon theme: "/usr/share/icons/Adwaita/22x22/legacy/" Invalid Context= "Legacy" line for icon theme: "/usr/share/icons/Adwaita/24x24/legacy/" Invalid Context= "Legacy" line for icon theme: "/usr/share/icons/Adwaita/32x32/legacy/" Invalid Context= "Legacy" line for icon theme: "/usr/share/icons/Adwaita/48x48/legacy/" Invalid Context= "Legacy" line for icon theme: "/usr/share/icons/Adwaita/256x256/legacy/" Invalid Context= "Legacy" line for icon theme: "/usr/share/icons/Adwaita/512x512/legacy/" Invalid Context= "Legacy" line for icon theme: "/usr/share/icons/Adwaita/scalable/legacy/" Invalid Context= "UI" line for icon theme: "/usr/share/icons/Adwaita/scalable/ui/" QGLXContext: Failed to create dummy context Invalid Context= "Legacy" line for icon theme: "/usr/share/icons/Adwaita/8x8/legacy/" Invalid Context= "Legacy" line for icon theme: "/usr/share/icons/Adwaita/16x16/legacy/" Invalid Context= "Legacy" line for icon theme: "/usr/share/icons/Adwaita/22x22/legacy/" Invalid Context= "Legacy" line for icon theme: "/usr/share/icons/Adwaita/24x24/legacy/" Invalid Context= "Legacy" line for icon theme: "/usr/share/icons/Adwaita/32x32/legacy/" Invalid Context= "Legacy" line for icon theme: "/usr/share/icons/Adwaita/48x48/legacy/" Invalid Context= "Legacy" line for icon theme: "/usr/share/icons/Adwaita/256x256/legacy/" Invalid Context= "Legacy" line for icon theme: "/usr/share/icons/Adwaita/512x512/legacy/" Invalid Context= "Legacy" line for icon theme: "/usr/share/icons/Adwaita/scalable/legacy/" Invalid Context= "UI" line for icon theme: "/usr/share/icons/Adwaita/scalable/ui/" failed to acquire GL context to resolve capabilities, using defaults.. adding empty sources model QStandardItemModel(0x561b604e2a20) no packages for "org.kde.plasma.quicklaunch" no packages for "org.kde.plasma.systemloadviewer" no packages for "org.kde.plasma.showActivityManager" no packages for "libgphoto2" no packages for "org.kde.plasma.grouping" no packages for "org.kde.plasma.diskquota" no packages for "org.kde.plasma.timer" no packages for "org.kde.kscreen" no packages for "libu2f-udev" no packages for "org.kde.plasma.appmenu" no packages for "org.kde.plasma.kimpanel" no packages for "org.cockpit_project.cockpit" no packages for "im.riot.webapp" invalid kns backend!
