crash dump 1

Just random crashes throughout the day with nothing obvious to correlate them. I am attaching two dumps - maybe they can help narrow things down.

Title to be updated to be more specific once a more exact root cause has been identified.

Operating System: Arch Linux

crash dump 2
Comment 2 Pawel 2023-01-25 12:44:14 UTC 
ok, the crashes might be related to the fact that the kernel was updated from 6.1.7 to 6.1.8 but the machine was not restarted. Still I think plasmashell should be more resistant to crashes in such environments but feel free to set me straight.

In the future, please file a different bug report for each plasma crash, as they will all end up having different root causes. Two out of three are Bug 462431; please file a new bug report for anything without "WeatherApplet::~WeatherApplet()" in it. Thanks!

hi Nate,

Thanks, sure.

How can I determine where the crash occurred based on the dump? There is a lot of information there and I am not sure how to extract the pertinent data.

It can be quite challenging without experience. In general I'd say always file a new bug report for each crash; it's not safe to assume multiple crashes are the same thing or have the same root cause. The KDE bug triagers will figure that out. :)
