Is there a user-facing portal problem associated with this? Or are you only reporting the error in the log?
Please forgive my ignorance, but I don't understand what you mean by a "portal problem".
xdg-desktop-portal is a tool to offer services to portal-using apps, such as those from Flatpak. I'm asking if you see an actual problem with any of these apps, or if this bug report is simply reporting the existence of a line in the log that you found suspicious.
The apps are not a problem. The fact that KDE dies periodically is a problem.
