Every time when my laptop has low power or can't connect to network, kde notification will pop up without any information and then all plasmas will freeze while other applications still run well. I use Archlinux with Nvidia card and installed the driver(nouveau) for my card. Reproducible: Always
Can you try to get a backtrace, please?
In the bug title you mention "crash", in the report you mention "freeze". So does it freeze (clicking doesn't do anything) or does it crash (panels and background disappear)? I think this might be related to bug 341951.
(In reply to Kai Uwe Broulik from comment #1) > Can you try to get a backtrace, please? It needs the file's path,but I don't know the specific path of kwrited or knotification. If I run gdb with backtrace option directly,there is no stack!!! Are you use archlinux?

Are you sure it's related to intel video driver as my drivers are up-to-date! Something different is that plasma gets frozen when there are nm connection's fault and low power even though I'm working!!! It's annoying and unreceptable! Find out what's wrong and fix it, please!
No I'm not sure it's related. It does have the same symptoms though. Best help you can provide at this point is to attach gdb to the running plasmashell and get the stack of where it is stuck. Do: $ gdb --pid `pidof plasmashell` if that gives you something about ptrace_scope and not having privillegies, you can either repeat with sudo or follow the ptrace_scope advice. Once you're in gdb, do: > thread apply all bt and post the output please.

I don't think it's related to intel driver! Because other pop-up notifications(etc usb and music player) work normally except power manager and network manager. By the way, if I disable popup notifications of power and network, plasma won't freeze. Process ID of plasmashell is 713. Hope it can help you slove this issue.

That's a good progress. Now if only you could install debug packages for libKF5Plasma and libQt5Core and libQt5Quick, that would show more precise data, this has lots of "??" which isn't helpful. I don't know how those debug packages are named on arch though, so you'll have to do a bit of a guess work or ask in a forum or some such. Once you have those debug symbols, please repeat the gdb step and post updated backtrace, then we'll see what's up. Thanks
