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. -- Backtrace: Application: KIO Client (kde-open5), signal: Aborted [KCrash Handler] #4 0x00007f7884b6e292 in raise () from /lib64/libc.so.6 #5 0x00007f7884b578a4 in abort () from /lib64/libc.so.6 #6 0x00007f7884fd042d in QMessageLogger::fatal(char const*, ...) const () from /lib64/libQt5Core.so.5 #7 0x00007f78810d6ef3 in QtWaylandClient::QWaylandDisplay::checkError() const [clone .cold] () from /lib64/libQt5WaylandClient.so.5 #8 0x00007f78810e56fa in QtWaylandClient::QWaylandDisplay::flushRequests() () from /lib64/libQt5WaylandClient.so.5 #9 0x00007f78851ce4fd in void doActivate<false>(QObject*, int, void**) () from /lib64/libQt5Core.so.5 #10 0x00007f78851ea6d2 in QEventDispatcherGlib::processEvents(QFlags<QEventLoop::ProcessEventsFlag>) () from /lib64/libQt5Core.so.5 #11 0x00007f788519c9b2 in QEventLoop::exec(QFlags<QEventLoop::ProcessEventsFlag>) () from /lib64/libQt5Core.so.5 #12 0x00007f78851a4544 in QCoreApplication::exec() () from /lib64/libQt5Core.so.5 #13 0x000055c9322474f5 in main () [Inferior 1 (process 2370) detached] Possible duplicates by query: bug 436863, bug 435427, bug 433524, bug 432084, bug 431077.

A lot has changed since then, and I don't recommend using the Wayland session in any Plasma version prior to 5.23. Can you try again in 5.23 to see if it's still happening? Thanks!

The X11 session isn't working much better than the Wayland session, and I can't run much of anything on this VM. I think we should close this bug, because I think my VM setup is the real problem, and there doesn't seem to be a way for me to provide more useful info. Thanks anyhow!
OK, thanks for checking again.
