Closed issue by Fyrenic on void-packages repository

https://github.com/void-linux/void-packages/issues/703

Description:
### System

* xuname: Void 4.16.14_1 x86_64 GenuineIntel uptodate rrrrmmn
* package: knewstuff-5.43.0_1 (probably affecting all versions)

### Expected Behavior

knewstuff should fetch metadata to display themes and icons from store.kde.org.

### Actual Behavior

knewstuff freezes and therefore locks up any program that calls it (like Yakuake).

**This only happens, when the computer is connected to the internet.** When it is not connected to the internet, the `Addon Installer` opens up as it should and it does not lock up.

### Steps to reproduce the behavior

* Install `yakuake`
* Run `yakuake` and open the `Configure` Window
* Go to `Appearance` and click on `Get new Skins`
* Application locks up
