            Bug ID: 478334
           Summary: KDE(?) crashes on first boot after fresh reinstall
    Classification: Applications
           Product: Discover
           Version: 5.27.9
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: discover
          Assignee: plasma-b...@kde.org
          Reporter: mikae...@yahoo.com
                CC: aleix...@kde.org
  Target Milestone: ---

Application: DiscoverNotifier (5.27.9)

Qt Version: 5.15.11
Frameworks Version: 5.111.0
Operating System: Linux 6.2.9-300.fc38.x86_64 x86_64
Windowing System: X11
Distribution: Fedora Linux 39 (KDE Plasma)
DrKonqi: 5.27.9 [KCrashBackend]

-- Information about the crash:
Fresh install of Fedora38's KDE system. On starting the DE (Plasma X11), I get
a discover notifier about a crash, and nothing KDE-related appears to start (no
panel, no background. The only exception is this crash handler, and the
"welcome to KDE Plasma" dialog.). 
I cannot figure out how to start any applications (RMB does nothing, ALT+F1
does nothing, ALT+F2 gets the "search" dropdown (KRunner?), but any keyboard
press causes it to disappear again. TTY works, and that way I ran a
system-upgrade to Fedora 39. It behaves identically.
I also tried Plasma Wayland (after login, I get a black screen with nothing but
a mouse pointer - for about one second. After that, it switches to what looks
like a non-graphical window for one second until the black screen with the
mouse pointer reappears. Repeat ad infinitum).
Fair to be said that this might be unrelated to KDE: I have the same problem
and symptoms in XFCE (but not in LXDE). I have yet to install and try Gnome.

The crash can be reproduced every time.
