Description Allen Winter 2024-09-24 14:22:44 UTC 
Using a recently hand-built Kate (within the last week)

I ran `eject /dev/sr0` from a command line and I think that had something to do with the crash

Here's the backtrace:
```

verified.  as soon as I run `eject /dev/sr0` from a konsole => Kate crashes

Hello,
Thanks for this merge, but I don't understand what the solution is for my
crash problem, which only occurs when a DVD is ejected, not for CDs, and
which doesn't specifically bug an application, but the whole system.
Remember that I have the same problem on another machine with the same kde
neon.
Thanks,
François-Marie Zwank

This was in KDE Frameworks, which sits underneath a whole array of KDE software, including Plasma itself and individual applications. On my system, this bug manifested as both Plasma and Dolphin crashing, but I believe it's all connected to this Frameworks issue. Note that it's specific to how file systems are handled, so a device without a file system like an audio CD shouldn't trigger the bug (e.g. it's not literally the action of ejecting the disc from the drive that's causing it, but how the system is responding to the file system disappearing).

Hope that helps,

Thanks
Comment 13 Patrick Silva 2024-11-05 10:54:52 UTC 
Was this fix already applied to neon unstable? I'm asking because the crash persists.

Operating System: KDE neon Unstable Edition
KDE Plasma Version: 6.2.80
KDE Frameworks Version: 6.8.0
Qt Version: 6.8.0
Graphics Platform: Wayland

I'm sorry to hear it's still crashing for you. Can you attach a fresh backtrace so we can see if it's the same code that's affected?
Comment 15 Patrick Silva 2024-11-06 19:52:25 UTC 
the backtrace of kded6 process that crashes together when ejecting a unmounted blu-ray disc:

Thanks for the backtrace. That does indeed look like a different crash. Can you please open a new bug report and paste that backtrace into it? Thanks!

Your Solid is from October 15. The fix was merged October 19
Comment 20 Patrick Silva 2024-11-07 10:34:59 UTC 
Unfortunately updates are considerably delayed on neon unstable.  :(
Thank you for clarifying, Nicolas.

Can confirm that the bug is fixed after updating to frameworks 6.8. \o/

Thank you all.

I'm sorry to hear this is still not fixed for you on NEON. If you can still reproduce the crash, please open a new report and attach a new backtrace. Sometimes the same thing can crash for different reasons or different parts of the code. We need the backtrace to determine what's happening on your install. Merci!
Comment 26 zed556@gmail.com 2024-11-12 19:26:40 UTC 
Hello,

Bug fixed since upgrading neon to frameworks 6.8.
But the notification for DVDs is not yet up to date.

Good evening
