            Bug ID: 436939
           Summary: startkde: "Could not start Plasma session" xmessage in
                    Wayland session in VirtualBox
           Product: kde
           Version: unspecified
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: aer0usa at gmail.com
  Target Milestone: ---

Application: kde-open5 (5.21.3)

Qt Version: 5.15.2
Frameworks Version: 5.80.0
Operating System: Linux 5.11.12-300.fc34.x86_64 x86_64
Windowing System: Wayland
Drkonqi Version: 5.21.3
Distribution: Fedora 34 (KDE Plasma)

-- Information about the crash:
- What I was doing when the application crashed:
I had just installed Fedora 34 Plasma in a VM in VirutualBox. I added the Guest
Additions CD to the VM, and I was mounting the CD when the session went black,
and showed an xmessage dialog with the message "startkde: Could not start
Plasma session." I am running a Wayland session.
FWIW, the host is Ubuntu MATE 20.04.2
Also FWIW, I saw this a few times during installation, and using an Xsession
worked better.

- Unusual behavior I noticed:
The black screen with xmessage dialog described above.
Thanks!

The reporter is unsure if this crash is reproducible.
