crash report by the KDE Crash Report tool

SUMMARY
I am experiencing issues with pdf-export for the flatpak version 1.8.10 of md.obsidian.Obsidian.

The issue is very much the same as here https://forum.obsidian.md/t/export-to-pdf-fails-on-kubuntu/95039  except the solution proposed does not work for me (installing xdg-desktop-portal-gtk)

The dolphin dialog appears briefly and quickly disappears, followed by the xdg-desktop-portal-kde Crash notification. Also occurs in sandbox vault. Also occurs from the binary from the appimage.
I have raised this to the dicord of Obsidian, but I was told, quote:
```
That's interesting I don't see it crash, but I have to give it a full path
I think you should file a bug with the KDE team they are extremely good at fixing them fast
```

STEPS TO REPRODUCE
1. install Obsidian md
2. use the sandbox vault (https://help.obsidian.md/sandbox)
3. open the command palette and find "Export to PDF"
4. click the export button 

OBSERVED RESULT
xdg-desktop-portal-kde crashes.
dolphin window closes and I cannot save the pdf

EXPECTED RESULT
not crashing. 
being able to save the file
