KCrash: Arguments: /usr/bin/plasmashell 

Plasmashell goes black (leaving the saved session apps open) 

Then all these messages repeat.

Restarting plasmashell manually by any method (eg exiting KDE and restarting, restarting from konsole, etc.) all have the same result. 


Researting plasmashell manually from konsole 

EXPECTED RESULT

plasmashell should not crash

ADDITIONAL INFORMATION
Comment 1 Bug Janitor Service 2022-11-21 14:33:30 UTC 
Thank you for the bug report!

Please note that Plasma 5.25.5 is not supported for much longer by KDE; supported versions are 5.24, and 5.26 or newer.

If at all possible please upgrade to a supported version and verify that the bug is still happening there.

If you're unsure how to do this, contact your distributor about it.
Comment 2 Jonathan E. Snow 2022-11-25 22:01:47 UTC 
Upgraded to "unstable" 5.26.3: Please note the identical c++ error message and failed assertion. This should never happen, even when the user misconfigures. See upgraded version list below:

 * Messages for package kde-plasma/kwin-5.26.3:

 * Install additional packages for optional runtime features:
 *   x11-misc/colord for color management support
 * 
 * In Plasma 5.20, default behavior of the Task Switcher to move minimised
 * windows to the end of the list was changed so that it remains in the
 * original order. To revert to the well established behavior:
 * 
 *  - Edit ~/.config/kwinrc
 *  - Find [TabBox] section
 *  - Add "MoveMinimizedWindowsToEndOfTabBoxFocusChain=true"

 * Messages for package kde-plasma/plasma-workspace-5.26.3-r1:

 * To enable gpg-agent and/or ssh-agent in Plasma sessions,
 * edit /etc/xdg/plasma-workspace/env/10-agent-startup.sh
 * and /etc/xdg/plasma-workspace/shutdown/10-agent-shutdown.sh

 * GNU info directory index is up-to-date.
 * After world updates, it is important to remove obsolete packages with
 * emerge --depclean. Refer to `man emerge` for more information.

Comment 5 Jonathan E. Snow 2022-11-27 17:24:00 UTC 
Workaround found: 

As you can see in the emerge --info above, qtcore is compiled with -Ofast. If compiled with -O2 the issue resolves. I see this as an opportunity for KDE to figure out how not to have that happen (I suspect a call to the string to double function with a null string is getting optimized away), and for qt to -Ofast-proof their code. 

So, please don't just mark this resolved. You can break everything pretty easily and reliably with a by compiling qtcore with -Ofast, which is not *that* crazy an optimization set. All of kde works with it. It happens not in some essential KDE component, but when setting up the wisgets in plasmashell. Rather than having plasmashell crash, whatever is causing it should be detected and averted (and the bug propagated to qt). But it's not my job. Thanks KDE for this great software.
Comment 6 Nate Graham 2022-11-30 21:05:34 UTC 
Thanks for all the logging, but as the message in the SUMMARY section says, what we really need is a symbolicated backtrace of the crash. Can you attach one?
