can't seem to reproduce right now. from the bt seems like an assert: what does the terminal output say when the crash occurs? ah, looking better at it, "Object %p destroyed while one of its QML signal handlers is in progress.\nMost likely the object was deleted synchronously (use QObject::deleteLater() instead), or the application is running a nested e" might be just another one of those signal handlers during destructor? Can't reproduce anymore. It must have gotten fixed by something recently. Probably this was the same as Bug 474385 all along. *** This bug has been marked as a duplicate of bug 474385 *** |
Plasma 6 git master, Wayland, 200% scale, vertical left screen edge panel, one screen. STEPS TO REPRODUCE 1. Add Analog Clock widget to panel 2. Enter edit mode 3. Hover over Analog Clock and click "Delete" 4. Close the notification asking me if I want to undo deleting the widget OBSERVED RESULT plasmashell crashes 100% of the time with the following backtrace: #0 __GI___pthread_sigmask (how=1,
