When opening KGet using a menu launcher, nothing happens, i.e. no GUI is launched. Upon inspecting processes, I can see that KGet is running, although I can’t see any GUI. It does not in system tray either.
Invoking KGet through the terminal, I get the following:
[user@machine ~]$ kget
Icon theme "Tela-dark-geen" not found.
Icon theme "Papirus-Dark" not found.
Icon theme "Zafiro" not found.
Icon theme "ubuntu-mono-dark" not found.
Icon theme "Mint-X" not found.
Icon theme "elementary" not found.

I don’t understand why it is requesting those packages since I am in Manjaro KDE? Also, I have no clue how to go about the QWidget error.
I have reinstalled the KGet but that didn’t not solve the issue.
Although I appreciate the reply, I am looking to solve and be able to use the native KDE downloader. Thanks anyway
Try removing those themes from the inherits line in ~/.themes/[your_current_theme]/index.theme. Guessing you don’t have those installed anymore.
Those themes are not anywhere in the suggested location. I never had them installed to start with 
Hi all,
quick update on my part.
I also encountered this issue today on a fresh Install of Manjaro. Themes do not seem to cause this issue.

Deleting the config folder solved the issue for me.
$ rm -r .config/kgetrc
That worked @david.m, thank you.
