KDE Plasma - Everything is crashing lately?

Ask Fedora
1

Since the last one or two dnf updates in the last month, I’ve noticed desktop apps are crashing a lot (I think they are segfaulting, occasionally they choose to share that info if I start them from a terminal.)

Pretty much all apps I use are doing this - Chrome, LIbreoffice, Okular, Konsole, etc. The crash seems to happen when closing a file chooser dialog with “OK”, and often the app that crashes is not the one I’m choosing a file for.

I tried switching back to Xorg from Wayland, didn’t seem to make a difference.

Anyone else seeing this?

What do the system and user logs contain when the crashing happens?

You can use sudo coredumpctl to find out what crashed and then get details that should help identify a possible cause.

Well, it looks like some of my cores are being kept after all …

The latest libreoffice was running in a terminal:

> kf.kio.filewidgets.kfilefiltercombo: KFileFilterCombo::setCurrentFilter: Could not find file filter KFileFilter(MIME patterns: QList() File patterns: QList("*.ods") label: "ODF Spreadsheet (.ods)")
> ....

I don’t have all the extra stuff I need to get anything useful out of gdb, but I’m going to skip that for now and see if something gets patched soon.

We are not hearing about this issue from other people yet.
That suggests it’s something about your system that is the cause.

If you can get to the point of getting stack trace out of the crashes it will go a long way to help figure out what is wrong.

Thanks for the encouragement. There is a big pile of debuginfo to be downloaded …

I did switch back to the “native” file dialogs in Libreoffice, and so far no crashes.

Don’t know if it helps, but seeing that you’re on Plasma 6.3.3 – I’ve had a very unstable system with that version too, and upgrading to Plasma 6.3.4 solved it for me. Is 6.3.4 available for F40? (I’m on F41.)

6.3.4 isn’t posted to F40 yet.

I just got a reasonable stack from the terminal. In this case LIbreoffice crashed while I was selecting a file in Chrome. This has to do with message passing between apps and the window manager, doubt there is much I can do for now (except upgrade.)

We will need other stack traces to see if there is a pattern.

Would mark as solution: Upgrading to F41 has either made this behavior stop or else it is infequent enough that it hasn’t occurred in the three days since the upgrade.

Glad you have a stable system again! :+1: :smiley:
