Bug 474529

SUMMARY
***
The first time I opened Neochat today, it launched, but when I clicked on a chat to open it, it crashed. Since then it directly crashes after launch (chats are visible for a brief moment).
When I launched it from the command line with `flatpak run org.kde.neochat`, I got the following output:
```
