Description Isaac Cohen 2025-09-07 00:20:37 UTC

SUMMARY
When I double click on the dictionary widget, I get a black screen with just a mouse

STEPS TO REPRODUCE
1) Go to the desktop
2) Right click and select "Enter Edit Mode"
3) Scroll down and select "Dictionary"
4) Click "Exit Edit Mode"
5) Double click on the dictionary

OBSERVED RESULT
Apparent crash

EXPECTED RESULT
No crash

If you run into this problem and Plasma crashes, rebooting won't help. You'll just get the same black screen with a mouse. Here's what you can do to fix it:
1) Cntrl-Alt-F3 to get a command line shell
2) Login
3) nano .config/plasma-org.kde.plasma.desktop-appletsrc
4) Remove these lines:
[Containments][1][Applets][35]
immutability=1
plugin=org.kde.plasma_applet_dict

5) reboot

Comment 2 Nate Graham 2025-09-17 22:23:46 UTC

Oh wow, I can reproduce this issue on current git master too, and it's really bad. Plasmashell crashes, doesn't restart, and then crashes again (with the same backtrace) when I try to launch it manually.

Here's the backtrace, which looks to be mostly in QtWebEngine:

Trying to launch plasmashell manually yields this:

In order to recover, I need to manually remove the org.kde.plasma_applet_dict item from my ~/.config/plasma-org.kde.plasma.desktop-appletsrc file.

And even clicking the widget once triggers this issue. No double-click required for me. I can also trigger the issue if I try to resize it at all.

This appears to be a very dangerous widget.

Upgrading to Critical since this basically bricks your system unless you're a super duper expert who knows where Plasma's config file lives, potentially how to edit it using non-GUI tools, and which exact thing to remove.

Ahh, I found Bug 502199. It's an AppArmor issue. I'm able to reproduce it now because I'm using KDE Linux which has AppArmor enabled. We'll fix this in KDE Linux, but affected people on other distros will need fixes from their own distros as well.
