New crash information added by DrKonqi
DrKonqi auto-attaching complete backtrace.
To reproduce: 1. Place a pie chart on the desktop. 2. Add "total usage" and "average CPU temperature" sensors. 3. Click on colour-box of "CPU temp" sensor to bring up the colour palette selector. 4. Choose a different colour, click apply. 5. Crash, but not always. Sometimes it works. Doing this also produced strange behaviour with the configuration of other sensors running other panels -- their sensor configs were cleared. The applet was still there, but the the "Sensor" list was empty. This is probably a plasma desktop config file(s) related bug.

0x00007fe03d716750 in ??? () #27 0x0000000000000000 in ??? () I can't immediately reproduce the crash with Qt 6.10. Given that the backtrace is entirely in Qt, which is going to be a Qt issue. Can you re-open this if you still encounter it at all with Qt 6.10 or later? Thanks a lot! |
