Description RicardoPQ 2020-10-07 18:53:41 UTC

Application: plasmashell (5.18.5)

Qt Version: 5.13.2
Frameworks Version: 5.73.0
Operating System: Linux 5.8.13-100.fc31.x86_64 x86_64
Windowing system: X11
Distribution: Fedora 31 (KDE Plasma)

-- Information about the crash:
- What I was doing when the application crashed:

It just happens after a fresh restart.

The only "weird" thing I've done recently was to install VMware Player, and I was able to see that it installed some "kernel modules". I've uninstalled it, but still the same.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 2 RicardoPQ 2020-10-07 19:23:08 UTC

I think I might have solved it by installing "qt5-qtdeclarative-5.13.2-1.fc31.i686". I did it because I saw in the Backtrace some messages saying "at /lib64/libQt5Quick.so.5", and found that this is some library from the package qt5-qtdeclarative, tried to reinstall but then dnf said that the package wasn't installed. So, I installed it, rebooted, and so far it hasn't failed again.

Comment 3 Nate Graham 2020-10-07 19:28:57 UTC

Yes, that's a requirement for Plasma to work properly. :)

If your distro didn't mark this as a dependency, you should file a bug on them to improve their Plasma packaging.
