Description Matthias Kuhn 2025-01-10 06:58:17 UTC

Qca softstore provider crashes here when being called through `supportedFeatures()` on macos, stack below.

```
Thread 13 Crashed:: Thread (pooled)

3   libqca.2.3.7.dylib            	       0x108d7ba18 QCA::supportedFeatures() + 216
```

If I remove the softstore plugin, the crash disappears.

We are in the process of phasing out QCA.

I would suggest you don't use it in your non KDE app and if this is a KDE app i suggest you help with the process of not using QCA anymore.

Thank you for the information, this is from building QGIS, which does not have an exit strategy yet.
