Description

Hello,

after the weekly updates (23.02.2019) on my Solus Plasma machine every qt application crashed.
Thanks to the rollback system I was able to restore the machine.
Here's the dolphin crash log:

Any idea what's causing the problem?

Strange: also got Solus Plasma on the pc at home. Btw. this installation is based on the very first iso (patreon iso) and the 'troublemaker' is based on the latest plasma-test-iso.

Can you give us the update log of the sync from eopkg hs ?

I did a fresh install with the test iso and a full update and I cannot reproduce this issue.

Could you test if this issue happens as well as with a new user?

LostSouls added a comment.Feb 25 2019, 10:32 AM

Works fine with a new user!
So I removed the widgets from the desktop, deleted the old task bar and created a new standard task bar.
Still crashing!

What else could it be if it's not the task bar and the desktop plasmoids?

there's likely some config file or cache in your homedir that plasma isn't able to read in this version

@LostSouls are you maybe Froz1984 on reddit?

LostSouls added a comment.Feb 25 2019, 6:37 PM

No, I'm not Froz1984.
Btw. same happened right now with my home computer. Wasn't aware that it hasn't updated yet. Thought there's already been updates during the weekend. At least my Budgie installation got updates on Fr/Sa.

We did not had any sync last Friday/Saturday.

I'd advise trying to remove any kde/plasma config and try resetting the desktop to default.

so please do the following

Backup .config file

mv .config config.bak
cd info .config and delete any kde and plasma files/folders + Trolltech.conf

Backup .kde folder
mv .config config.bak

delete .kde folder
rm -rf .kde

delete files/folders inside .cache
rm -rf .cache/*

reboot you can do this via TTY but I tested this and it didn't cause any issues while doing this on a running desktop

For me I could identify the "Global Menu" Widget as the reason for that problem. At least at Home, didn't check, for now, if it is the same on the work machine. Had that widget in the Latte-Dock and the Plasma panel.

Edit:
After building and adding applet-window-appmenu to my latte-dock I had the same issue again.

Girtablulu moved this task from Backlog to Package Fixes on the Software board.

This should be fixed when I can land Plasma 5.15

LostSouls added a comment.EditedMar 11 2019, 11:34 AM

Followed @xllndr advice.
Removed global menu from the windows bar and updates worked perfectly.

Girtablulu claimed this task.

Plasma 5.15.2 is in unstable, should be fixed on the next sync
