It could have been a network change notification - IIRC I had a few notifications at the same time, and the crashed happened a few seconds after closing the notification, then the crash dialog was sitting unattended for a while as I was dealing with more urgent stuff. I may be misremembering. Have you encountered this on Plasma 6? I can't pretend to remember what this was about, and I'm now on Plasma 6 so if there is any indication that this crash is Plasma 5 specific - then I'm happy to let it go. If I get interesting crashes, I'll report them in a new ticket. |
Created attachment 161207 [details] DrKonqi crash data SUMMARY I believe I got this from closing a "panel was removed" plasma notification.
