Thanks for the crash report. As the message at the top of the summary says, if something crashed, we need a backtrace of it so we can figure out what's going on. Can you please attach a backtrace of the crash, as detailed in https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports ?

Thanks.

Backtrace from Plasma crash

(In reply to TraceyC from comment #1)

My apologies, I have attached the backtrace now. Hope it helps!

I don't see any tangible relation between the crash and changing the time. I'd be surprised if it's really related

After further testing, it seems to only crash when connected to internet with a wrong time. If i turn wifi off, there are no issues. I can show a video of what I'm doing if that helps.

I have recorded a video of the issue, and uploaded it here: https://www.errin.dev/Wrong-time-plasmashell-crash.mp4 
It is a slightly unusual one. My assumption is that a widget or app that has to contact the internet, and loads when plasmashell does is not liking having a significantly wrong time.

My bug report was flagged as a duplicate and it does seem like it's the same bug, but it's interesting how it's triggered differently.
In my case (also happens to be a framework, but amd) I have it when resuming from standby). Interesting...

WidgetsAskUserActionHandler: show the SSL error dialog on the GUI thread

askIgnoreSslErrors() can be called from a non-GUI thread (e.g. the weather
ion runs its KIO jobs on a worker thread), where it constructed the
KMessageDialog off the GUI thread and crashed while painting it.

Marshal the dialog onto the GUI thread with QMetaObject::invokeMethod(qGuiApp,
...), like every other handler in this class already does.

I guess the time change triggered an SSL error, and the crash happened whule handling that

Adding the MR link for reference, since it was not automatically picked up here. Most likely since bugzilla  was down when the MR was raised.
