Details

Description:
Using KDE Plasma 5.12 on a recently installed Arch Linux. When right clicking in the Application Menu on a program, say to add it to favorites.
The panel and application menu freezes until I kill off the plasmashell process

I have bumblebee installed on my Nvidia Optimus laptop if that is important

Additional info:

* config and/or log files etc: Can't seem to start plasmashell from the debugger per my expertise, so I can't really give much of a stack trace


Steps to reproduce:

1. Switch out the default kickoff menu with the alternative application menu
2. Search for an application.
3. Right click and be forced to open Konsole to kill off the frozen plasmashell instance.
This task depends upon

I figured out why it wasn't running in gdb, I should have run plasmashell instead of passing it into kstart5.

Anyways, this is the output I have been getting when it freezes

(process:21943): GLib-GObject-WARNING **: 23:25:24.779: cannot register existing type 'AsLaunchable'

(process:21943): GLib-GObject-WARNING **: 23:25:24.779: cannot add private field to invalid (non-instantiatable) type '<invalid>'

Run "gdb plasmawindowed", then "(gdb) r org.kde.plasma.kickoff", hit ctrl+C when it freezes, and get a backtrace

Does appstream work at all? Try eg. "appstreamcli search plasma"
Comment by Stefano Coronado (stefnix) - Saturday, 05 January 2019, 17:08 GMT
Yes, appstream works fine. The issue here may be flatpak

edit: wrong bug thread.

found only one archive in this directory, and it's too big to attach

Then send it directly by email (arojas@archlinux.org)

This is caused by a symbol clash between appstream and appstream-glib. Related upstream reports:

Should be fixed with https://github.com/flatpak/flatpak/commit/f9c6a769ef30a3a33038ec91f080197a0bf418a5

…which landed in [extra] in flatpak-1.1.3-1.
