- GDB gives the following stack trace:
```

```
The function `QMimeType::inherits(QString const&) const ()` runs forever and
never returns.

- It turns out that one file
(`~/.local/share/mime/packages/appimagekit_95f6eff3ef1e2ad046cfd66717eee4da_freedesktop.org.xml`)
was responsible for the issue. Deleting or moving the file solves the problem.
