-- Information about the crash:
Sorry if this is not specific enough, but Plasmashell keeps crashing between service restarts and reboots, and I don't know the root cause or what to do next.

How can I provide more info on this issue?

The crash can be reproduced every time.

Are you using proxy?
Comment 2 Nate Graham 2023-04-04 19:34:09 UTC
Can you clarify what exactly "between service restarts and reboots" means? When specifically does Plasma crash?
Comment 3 Nate Graham 2023-04-04 19:37:36 UTC
Oh also, does the issue go away if you disable (don't hide, disable) the Media Player widget in your Panel or System Tray? Or if you disable Plasma Browser Integration?

Sure. Just a quick update: I can't replicate this problem anymore, but given that 1. I didn't fix it intentionally; 2. no updates were applied in the meantime, and 3. given the "catastrophic fault", I think it's worth investigating what caused it in the first place as someone else might experience it.

I attempted restarting plasmashell many times using both `kquitapp5 plasmashell && kstart5 plasmashell` and `systemctl --user restart plasma-plasmashell`. They had the same effect: plasma would start and crash up to three times within a few seconds before "giving up". Occasionally it would start without crashing, but only for a few seconds or minutes, and I don't know what would cause it to crash again.

Rebooting the entire system also had no effect: after the SDDM login screen plasma would eventually (if not instantly) crash.

If the problem resurfaces I can try disabling the browser integration and the media player in the system tray - I don't have one in the panel.

As in a web proxy? I most likely had the VPN enabled during the crashes. Could that be related to the problem?
Comment 7 Nate Graham 2023-04-04 20:30:51 UTC
Yep. Does it happen when you're not behind a VPN?
Comment 8 Lucas 2023-04-07 02:12:09 UTC

> Yep. Does it happen when you're not behind a VPN?

So the issue came back. It also happens when the VPN is off.

It still happened with the media tray icon disabled. I've now disabled the Plasma Integration extension and, so far, it hasn't crashed.
Comment 10 Nate Graham 2023-04-09 18:54:33 UTC
Thanks for the info.
Comment 11 Nate Graham 2023-04-09 19:13:42 UTC
We also have a report in Bug 467493 that the issue has gone away in Plasma 5.27.4. Can you upgrade to that version, keep plasma-browser-integration active, and see if it's fixed now? Thanks a lot!

Interesting, I was also running Jellyfin during the crashes. During the last few days I had integration disabled and the issue didn't show up. I'm now on 5.27.4 with Plasma Integration enabled again - I'll leave an update here in a few days. Thanks for the help!
