            Bug ID: 484739
           Summary: Crash on selecting default application
    Classification: Plasma
           Product: xdg-desktop-portal-kde

  Target Milestone: ---

Application: xdg-desktop-portal-kde (5.27.5)

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.1.0-18-amd64 x86_64

-- Information about the crash:
I opened a .txt file directly from my Firefox downloads menu. When prompted to
select the application to open the file with, I chose Kate and it opened fine.
I decided to close out and reopen the file again, this time checking the
"Always open with the chosen app" box. This time when I clicked on Kate, the
Portal window froze and then crashed.

The crash does not seem to be reproducible.
