| Sentry Crash Report: | |||
This isn't a notification KCM specific crash - I managed to reproduce the same crash (same signal in the same offending frame) in several other system settings modules, specifically just loading the KCMs (by clicking the labels) for at least these modules, immediately crashes the application: - Look and Feel - Workspace Theme - Colors - Icons - Window Decorations - Desktop Effects and probably more, I stopped at this point. Interestingly the following do not crash: Fonts, Font Management, Application Style, GNOME/GTK Application Style and others. *** Bug 407451 has been marked as a duplicate of this bug. *** It seems like this commit (https://phabricator.kde.org/R858:f7f99e8b8ca42c1036db4c25ce0488df2046b6a9) causes this crash. Hopefully we will get a revert or fix soon. Maybe fixed by https://phabricator.kde.org/D21153 ? I've added the patch there by hand, and it does indeed stops the KCM Notifications' "Configure applications" view from crashing, but everything else keeps crashing. I'm guessing we need more of those...

SUMMARY The "Applications" configuration option under the Notifications KCM ("Event Notifications and Actions", not the confusingly identically titled "Other Notifications" KCM), pressing the "Configure..." button causes an immediate crash. STEPS TO REPRODUCE 1. Open System Settings 2. Click the first "Notifications" icon 3. Click the "Configure..." button next the label "Applications" OBSERVED RESULT System Settings crashes EXPECTED RESULT Some dialog should probably open.
