Description Jeff Beardsley 2025-01-02 19:20:43 UTC 
SUMMARY

Starting this week (I suspect this began with the latest update) I have been unable to install new widgets on plasma desktop when running under Wayland.  Logging out and switching to X11 fixes the problem.

STEPS TO REPRODUCE
1. On Plasma Desktop, Enter Edit Mode (via desktop context menu, for instance). 
2. Choose "Add or Manage Widgets".
3. Drag any widget from the sidebar onto the desktop.

OBSERVED RESULT
Plasma Crashes (and restarts) if you are running Wayland.
OTOH, if running X11, it functions properly.

EXPECTED RESULT
Widget installed on desktop

Comment 1 Nate Graham 2025-01-02 19:59:51 UTC 
If something crashed, we need a backtrace of it so we can figure out what's going on. Can you please attach a backtrace of the crash using the `coredumpctl` command-line program, as detailed in https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl?

There's no pasting the complete dump in here, I cut it off after 5000 lines.
Here's the first 100 lines -- I am guessing we're looking at a infinite loop at plasmaquick/dialog.cpp:1489

Also, if it's useful to know, no widgets were already installed except for the default panel, as I had just removed .config/plasmashellrc and restarted (after witnessing other weirdness).
I tried installing the "Individual Core Usage" widget and the "Analog Clock," but both crashed in the same manner.

Does it happen in a new clean user account? I suspect it does, but it would be nice to be sure.

This looks quite odd to me. Are you by any chance using a fork of Breeze or any other non-default styling?

Seems to work fine in a fresh user account.

I don't recall which theme was in place when this happened (sorry, I change
themes alot).  In any case it was not Breeze.  While I was experimenting
this morning, my desktop became unusable so I removed .config/plasmashell,
and rebooted.  Now I am now running default breeze and that seems to work
fine.  I guess this issue really belongs to one of the themes

Comment 6 Nate Graham 2025-01-06 21:42:01 UTC 
Did you delete ~/.config/plasmashell, or move it aside? It would be nice to be able to compare old and new.

If you deleted it, could you try to narrow down which exact theme or tweak caused it? That would be really helpful.
