After updating to Plasma 6.5 (and later 6.5.1), my desktop crashes after some time. Looking at the logs, this appears to be what is outputted by `plasmashell` when crashing: ``` Nov 04 12:55:04 arch plasmashell[1947]: Connection to Wayland server timed out. Nov 04 12:55:05 arch plasmashell[1947]: QObject::connect(QObject, ConfigMonitor::Private): invalid nullptr parameter Nov 04 12:55:08 arch plasmashell[1947]: QQmlVMEMetaObject: Internal error - attempted to evaluate a function in an invalid context ``` The most I can deduce as a pattern is a lot of times, it occurs when my laptop attempts to reconnect to WiFi after waking from suspend, but beyond that, it appears to just randomly crash after some time. STEPS TO REPRODUCE 1. Open laptop and log in 2. Use laptop for a bit 3. Find Plasma crashes OBSERVED RESULT Plasma crashes EXPECTED RESULT Plasma not crashing SOFTWARE/OS VERSIONS Windows: macOS: (available in the Info Center app, or by running `kinfo` in a terminal window) Linux/KDE Plasma: Arch Linux (kernel version 6.17.7) KDE Plasma Version: 6.5.1 KDE Frameworks Version: 6.19.0 Qt Version: 6.10.0 ADDITIONAL INFORMATION While I run my system with the experimental Xe drivers, this bug occurs on both the Xe drivers and the stable i915 drivers
To add some more information, this didn't occur in Plasma 6.4, only Plasma 6.5
Thanks for the crash report. As the message at the top of the summary says, if something crashed, we need a backtrace of it so we can figure out what's going on. Can you please attach a backtrace of the crash using the coredumpctl command-line program, as detailed in https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl ? Thanks.

Unfortunately it seems no coredump was created. This is all I get ``` TIME PID UID GID SIG COREFILE EXE SIZE Sun 2025-10-26 00:41:08 CDT 155316 0 0 SIGABRT none /usr/bin/python3.13 - Sat 2025-10-25 23:51:26 CDT 136955 1000 1000 SIGABRT present /usr/bin/blenderlauncher 75.5K Sat 2025-10-25 23:51:25 CDT 136956 1000 1000 SIGABRT present /usr/bin/blenderlauncher 15.6M Mon 2025-10-20 15:51:09 CDT 32466 1000 1000 SIGSEGV missing /app/zen/zen - ```
Thanks for checking. If there's no coredump, then plasmashell didn't actually crash. Can you describe in a little more detail what you see when this bug happens?

Can you describe in a little more detail what you see when > this bug happens? When this bug occurs: 1. All widgets disappear, including the taskbar and wallpaper (so just a black screen) 2. Anything open in other workspaces also crashes, only windows in the currently active workspace remain - I'm able to resize them and position them thougb 3. Sometimes when ceeating a new tab in FireFox, the tab will crash 4. Trying to log out becomes impossible without a forced power off as the application launcher doesn't appear
Thanks for clarifying, that's helpful. It's odd that there's no coredump for plasmashell. I found a similar log message reported in bug 482768, where there *was* a crash, that was supposed to be fixed in 6.1.3. It may be that plasmashell is exiting in a way that prevents it from writing a core dump. Can you have a terminal running before seeing the bug or get to TTY with Ctrl+Alt+F3 when it happens? If so, can you run this while plasmashell is in this bugged state? sudo gdb -p $(pidof plasmashell) then type bt then press 'c' if it asks you if you want to continue paging Then copy-and-paste the output here. Thanks!
Ok it happened this time, and it seems to be when I try connecting to a WiFi network that requires guest login Coredump Backtrace: ``` PID: 4059 (plasmashell) UID: 1000 (mahid) GID: 1000 (mahid) Signal: 11 (SEGV) Timestamp: Sat 2025-11-15 13:22:20 CST (3min 38s ago) Command Line: /usr/bin/plasmashell --no-respawn Executable: /usr/bin/plasmashell Control Group: /user.slice/user-1000.slice/user@1000.service/session.slice/plasma-plasmashell.service Unit: user@1000.service User Unit: plasma-plasmashell.service Slice: user-1000.slice Owner UID: 1000 (mahid) Boot ID: ee8611178a6248bf9fcf79bc50ca426c Machine ID: 9770dcc152f4492cb8e2a190eb137ea0 Hostname: arch Storage: /var/lib/systemd/coredump/core.plasmashell.1000.ee8611178a6248bf9fcf79bc50ca426c.4059.1763234540000000.zst (present) Size on Disk: 25.5M Message: Process 4059 (plasmashell) of user 1000 dumped core.

Thanks for your reply, and the backtrace. That's useful. The folks more familiar with this area of the code will have to take a further look.
I'm not able to reproduce this crash on git-master on a wi-fi network that requires a password. Does it only happen on a guest network or any Wi-Fi network that requires a password?
I've only had this on guest networks
