Bug 489259

I tried to replicate this but can't, whether manually pressing the shortcut or keeping it pressed. I tried it with several images in the clipboard, I tried it with 31 megabytes of Lorem Ipsum plain text. I tried it with an empty clipboard. The only thing I got was fast flickering from the popup opening and closing so often.

Do you have an idea about specific circumstances that may have caused this? Does it happen reliably for you?

It happens at random frequency, sometimes first hit, sometimes 1 miss 1 hit, sometimes 2 or more miss then it occurs.

The only customized thing I have is setting 700 items as history for Klipper.

Is there any way apart from coredumpctl to retrieve the crash?

Can you share more information of your system?

System Settings -> About this system -> click copy details and paste them here

This was not present on 6.1.0, it happened after upgrading to 6.1.1, the problem is more aggressive on two laptops:

I have this same problem on my desktop. I don't know how else to debug it, but journalctl show me there errors after workspace crashing due to klipper:

Looks like the same issue as Bug 488515, but applied to this popup too.

FWIW I also cannot reproduce the issue by spamming Meta+V, albeit with my puny 20 item history.

Or maybe the fix for that issue happened to fix this one too? I see that that issue is only fixed for Plasma 6.2.

I also have this issue after updating to Plasma 6.1.1. I can get it to fail 50% of the time after having copied an image into the clipboard and then trying to press Meta+V three times.

I cannot reproduce it. What window is active and where is the cursor when you press Meta+V?

It happens everywhere, with Firefox, Kate... even with desktop visible and no app opened.

I have the same issue. I first thought it was because of the large amount of history I had set, which was 512 entries. But even after reducing the amount I still have this crash.

KDE Frameworks Version: 6.3.0

I also have this issue. I also get crashes when opening the debug console via "qdbus6 org.kde.KWin /KWin org.kde.KWin.showDebugConsole
" with the same error "QDBusError("org.freedesktop.DBus.Error.UnknownObject", "No such object path". General instability and freezes after upgrading to 6.1.1

This is the core dump I get from the clipboard

I'm also seeing this on Arch.

Steps to Replicate (For me):
- Press Meta+V to open clipboard selection list modal.
- Press Meta+V again while the paste modal is still visible

Caveats (For me):
- Plasmashell does not seem to crash if Meta+V is pressed and the clipboard popup modal is not focused.
  (This can be achieved by pressing Meta, keeping it held down until the Application Launcher to shows up, and then pressing V, so you can unfocus the popup/modal without dismissing it)

Uninformed Musings / Speculation as to cause (I am not a *KDE* developer):
I heard that keybinds only involving the Meta key were added recently, maybe it's related to that?
Another thought is that it might have do with Wayland and the concept of focus somehow (?).

Closing Thoughts:
I've seen other people in this thread that can cause this crash through a single press of Meta+V, I think I've experienced the crash when Meta+V is pressed, but I can't intentionally replicate this.

I can reproduce this reliably by :
- Pressing Meta+V 
- Clicking on the Search Bar on the modal 
- Pressing Meta+V

KDE Frameworks Version: 6.3.0
Qt Version: 6.7.2
Kernel Version: 6.9.7-zen1-1-zen (64-bit)
Graphics Platform: Wayland

I am able to reproduce consistently.
1. Press Meta+V
2. **Release Meta and V**
3. Press Meta+V
If using a 3-key shortcut, releasing only 2 of them cause the issue.
e.g. Maj+Alt+V ⇒ Release Maj+Alt ⇒ Press Maj+Alt

I am also able to reproduce the single press crash
1. Meta (open the Application Launcher)
2. Meta (close it), or open an application by using the keyboard or the mouse
3. (... Do whatever you want: nothing, wait, write, Alt+Tab, Meta+C; except explicit focus to a panel by clicking on it, or going to the/another desktop ...)
4. Press Meta+V

Summary: Meta+V try to open a dialog on closed/closing dialog

As a workaround, switch to the desktop/another virtual desktop before using Meta+V.
e.g. Meta+D+D, **Release all**, Meta+V
(Meta, Meta, Meta+D+D+V will crash)

The crash is gone after upgrading to qt6-wayland 6.7.2-2 both on Arch and Manjaro unstable.
