Comment 1 TraceyC 2026-01-20 16:21:24 UTC 
Thank you for the bug report. I'm not able to reproduce this on git-master. Unfortunately the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong:

#9  0x00007f9a4156ca49 in ??? () at /usr/lib/qt6/qml/org/kde/plasma/private/clipboard/libklipperplugin.so
#20 0x00007f9a8b798c0a in ??? () at /usr/lib/libPlasmaQuick.so.6
#36 0x00007f9a885e00e2 in ??? () at /usr/lib/libQt6Core.so.6

Could you please install debug packages and attach a new symbolicated backtrace generated by using `coredumpctl gdb` in a terminal window? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl for details about how to do this. Thanks again!
