Comment 1 Nate Graham 2020-09-15 18:35:28 UTC 
Crashing in KNSCore::XmlLoader::[other stuff]. Malformed theme metadata maybe? Either way, the GHNS window should be more resilient against this.
Comment 2 Alexander Lohnau 2020-09-15 18:40:02 UTC 
>Malformed theme metadata maybe? 

I can reproduce this every time: Click on the Get New Things button, close it really fast, click it again.

Only an issue with QWidgets as far as I can tell.

Still occurs on Frameworks 5.79.
Comment 10 Alexander Lohnau 2021-02-21 20:57:39 UTC 
It seems that Calligra uses the KNS components in a not so standard fashion. I will look into it.
