Frequent crashes in plasma-discover with libglib-2.0 errors

[Paul Schumacher]

Description:
I am experiencing frequent crashes with the application plasma-discover on Ubuntu 22.04.4 LTS. These crashes occur when I attempt to access the update functions within the Discover UI. Terminal outputs and system logs indicate issues with libglib-2.0, showing repeated trap int3 errors, which are typically used for debug breakpoints in development builds.

Expected Behavior:
Plasma Discover should run smoothly, allowing the management of software updates and installations without crashing.

Actual Behavior:
Discover crashes frequently, especially when trying to access the updates section or other specific parts of the application.

Steps Attempted:

Resetting configuration files for Discover.
Running Discover from the terminal to capture any error outputs.
System update and reinstallation of plasma-discover and its dependencies.
Analyzing system logs with journalctl, which showed repeated issues with libglib-2.0.

System and Package Information:

Ubuntu Version: 22.04.4 LTS
Package Versions:
    libglib2.0-0: Installed: 2.72.4-0ubuntu2.2
    plasma-discover: Installed: 5.24.7-0ubuntu0.1

This issue significantly impacts the functionality of the Discover application, hindering routine software management and updates. Any assistance or resolution would be greatly appreciated.

This solved my issue:

sudo apt remove --purge plasma-discover && sudo apt install plasma-discover

After that everything was working perfectly!
